What can I do to fix this?Show Answer If the equations are overlapping the text (they are probably all shifted downwards from where they should be) then you are probably using Internet Explorer 10 or Internet Explorer 11. To fix this problem you will need to put your browser in "Compatibly Mode" (see instructions below). Alternatively, you can view the pages in Chrome or Firefox as they should display properly in the latest versions of those browsers without any additional steps on your part. Put Internet Explorer 10 in Compatibility Mode Look to the right side of the address bar at the top of the Internet Explorer window. You should see an icon that looks like a piece of paper torn in half. Click on this and you have put the browser in Compatibility View for my site and the equations should display properly. Put Internet Explorer 11 in Compatibility Mode Look to the right side edge of the Internet Explorer window. You should see a gear icon (it should be right below the "x" icon for closing Internet Explorer). Click on this to open the Tools menu. Down towards the bottom of the Tools menu you should see the option "Compatibility View Settings". Select this option to open a dialog box. In the "Add this website" box Internet Explorer should already have filled in "lamar.edu" for you, if not fill that in. Then all you need to do is click the "Add" button and you will have put the browser in Compatibility View for my site and the equations should display properly. Can you help me with a problem/homework/ Short Answer : No. Long Answer : No. Long Answer with Explanation : I'm not trying to be a jerk with the previous two answers but the answer really is "No". Here's why. My first priority is always to help the students who have paid to be in one of my classes here at Lamar University (that is my job after all!). I also have quite a few duties in my department that keep me quite busy at times. All this means that I just don't have a lot of time to be helping random folks who contact me via this website. I would love to be able to help everyone but the reality is that I just don't have the time. So, because I can't help everyone who contacts me for help I don't answer any of the emails asking for help. Also, when I first started this site I did try to help as many as I could and quickly found that for a small group of people I was becoming a free tutor and was constantly being barraged with questions and requests for help. Unfortunately there were a small number of those as well that were VERY demanding of my time and generally did not understand that I was not going to be available 24 hours/day, 7 days/week for help. I really got tired of dealing with those kinds of people and that was one of the reasons (along with simply getting busier here at Lamar) that made me decide to quit answering any email asking for help. So, while I'd like to answer all emails for help, I can't and so I'm sorry to say that all emails requesting help will be ignored. Where are the answers/solutions to the Assignment Problems?Show Answer Answer/solutions to the assignment problems do not exist. Those are intended for use by instructors to assign for homework problems if they want to. Having solutions (and for many instructors even just having the answers) readily available would defeat the purpose of the problems. Please do not email asking for the solutions/answers as you won't get them from me. How do I download pdf versions of the pages?Show Answer There are a variety of ways to download pdf versions of the material on the site. From Content Page If you are on a particular content page hover/click on the "Downloads" menu item. You will be presented with a variety of links for pdf files associated with the page you are on. Included in the links will be links for the full Chapter and E-Book of the page you are on (if applicable) as well as links for the Notes, Practice Problems, Solutions to the Practice Problems and Assignment Problems. The links for the page you are on will be highlighted so you can easily find them. From Download Page All pdfs available for download can be found on the Download Page. Links to the download page can be found in the Download Menu, the Misc Links Menu and at the bottom of each page. Once on the Download Page simply select the topic you wish to download pdfs from. This will present you with another menu in which you can select the specific page you wish to download pdfs for. Once you have made a selection from this second menu up to four links (depending on whether or not practice and assignment problems are available for that page) will show up below the second menu that you can click on to initiate the download. From Site Map Page The Site Map Page for the site will contain a link for every pdf that is available for downloading. You can access the Site Map Page from the Misc Links Menu or from the link at the bottom of every page. Note for Internet Explorer Users If you are using Internet Explorer in all likelihood after clicking on a link to initiate a download a gold bar will appear at the bottom of your browser window that will allow you to open the pdf file or save it. I've found a typo in the material.Show Answer If you have found a typo or mistake on a page them please contact me and let me know of the typo/mistake. Please be as specific as possible in your report. Let me know what page you are on and just what you feel the typo/mistake is. It's kind of hard to find the potential typo if all you write is "The 2 in problem 1 should be a 3" (and yes I've gotten handful of typo reports like that...). Some of the equations are too small for me to see!Show Answer This is a problem with some of the equations on the site unfortunately. It is especially true for some exponents and occasionally a "double prime" 2nd derivative notation will look like a "single prime". You can click on any equation to get a larger view of the equation. Clicking on the larger equation will make it go away. If you are a mobile device (especially a phone) then the equations will appear very small. I am attempting to find a way around this but it is a function of the program that I use to convert the source documents to web pages and so I'm somewhat limited in what I can do. I am hoping they update the program in the future to address this. In the mean time you can sometimes get the pages to show larger versions of the equations if you flip your phone into landscape mode. Another option for many of the "small" equation issues (mobile or otherwise) is to download the pdf versions of the pages. These often do not suffer from the same problems. Is there any way to get a printable version of the solution to a particular Practice Problem?Show Answer Yes. If you want a printable version of a single problem solution all you need to do is click on the "[Solution]" link next to the problem to get the solution to show up in the solution pane and then from the "Solution Pane Options" select "Printable Version" and a printable version of that solution will appear in a new tab of your browser. Cheat Sheets and Tables Here is list of cheat sheets and tables that I've written. Most of these are pdf files and so you will need the Adobe Viewer to view them. You can download the latest version here. Algebra Cheat Sheet - [pdf] - This is as many common algebra facts, properties, formulas, and functions that I could think of. There is also a page of common algebra errors included. Currently the cheat sheet is four pages long. Algebra Cheat Sheet (Reduced) - [pdf] - This is the same cheat sheet as above except it has been reduced so that it will fit onto the front and back of a single piece of paper. It contains all the information that the normal sized cheat sheet does. Trig Cheat Sheet - [pdf] - Here is a set of common trig facts, properties and formulas. A unit circle (completely filled out) is also included. Currently this cheat sheet is four pages long. Trig Cheat Sheet (Reduced)- [pdf] - My standard trig cheat sheet reduced to fit onto the front and back of a single piece of paper. It contains all the information that the normal sized cheat sheet does. Calculus Cheat Sheets - Because of the size of this I've got a full version as well as several that are broken up by subject. Each cheat sheet comes in two forms, one in full sized and one that has been reduced so that two pages will one side of a piece of paper. All reduced cheat sheets contain the same information as the normal sized cheat sheets. Here are the various cheat sheets that I've got at this point. Complete Cheat Sheet - [Full Size] [Reduced] - This contains common facts, definitions, properties of limits, derivatives and integrals. Most of the information here is generally taught in a Calculus I course and there is some information that is generally taught in a Calculus II course. The full sized version is 11 pages Limits Cheat Sheet - [Full Size] [Reduced] - This is the limits portion of the Complete Cheat Sheet. The full sized version is 2 pages. Derivatives Cheat Sheet - [Full Size] [Reduced] - This is the derivatives portion of the Complete Cheat Sheet. The full sized version is 4 pages. Integrals Cheat Sheet - [Full Size] [Reduced] - This is the integrals portion of the Complete Cheat Sheet. The full sized version is 5 pages. Common Derivatives and Integrals - [pdf] - Here is a set of common derivatives and integrals that are used somewhat regularly in a Calculus I or Calculus II class. Also included are reminders on several integration techniques. Currently this cheat sheet is four pages long. Common Derivatives and Integrals (Reduced)- [pdf] - My common derivatives and integrals table reduced to fit onto the front and back of a single piece of paper. It contains all the information that the normal sized table does. Table of Laplace Transforms - [pdf] [html] - Here is a list of Laplace transforms for a differential equations class. This tables gives many of the commonly used Laplace transforms and formulas.
