You appear to be on a device with a "narrow" screen width (i.e. you are probably on a mobile phone). Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.

You can use the form below to send me a message. Your name and email address are optional but if you send an email that requires a reply from me that will be a little hard if you don't supply an email address!

Over the years I've gotten really busy with my duties here at Lamar University and just don't have the time to answer all the messages that I get so if you don't get a reply from me do not take it personally, I just got busy and didn't have time to reply to the message. I can assure you however that I do read all messages that I get. Two groups of messages that I never respond to anymore are requests for help with problems/homework/etc. and requests for solutions/answers to the Assignment problems. The reasoning for not replying to those messages can be found here.

If you are sending me a message about a typo or mistake in the material somewhere please include the course notes, section and Example (if applicable) where the typo/mistake is. I've gotten a few messages very similar to "The 1 in Example 2 should be a 3" and it is pretty much impossible to find those kinds of typos.

If you are an instructor looking to formally use some/all of this material in a course you are teaching please include the material you are looking to use, the approximate number of students who will be using the material, the school you are teaching at, the state your school is in (if you aren't in the US you don't need to worry about this) and the country you are in, if you aren't in the US. Also, I would like to know if the material will be considered as a primary or supplementary source for the students and if it is required or optional.

If you are a student looking to use the material as a supplement to your class you do not need to request permission to use the material as that is the purpose of me putting it online!

Your Name (optional)
Your Email Address (optional)
Friendly reminder. If you are sending me a message that requires/asks for a response from me please include your email address! I cannot read your mind and there is no way for this site to somehow magically know what your email address is. :) If you do not include your email address there is simply no way for me to respond to your message if I need to.

If you are requesting use the material as on official text for a class or some other use that requires my formal permission/approval and you don't include your email address I cannot (clearly) give permission/approval and you can't assume that no response from me means you have my permission/approval!
