Graphing Calculator – MathPac+ 8.8.4

Current Version: 8.8.4
Requires Android: 2.2 and up
Category: Education
v8.8.4 update:
v8.7.8 added 95% Confidence Bands to LinReg & LinReg T-test
v8.8.1 added landscape for Tablets, corrected issue with TVM Solver
I would like to give an explanation for all the recent updates: we had a computer crash. I am making new builds from the back-up files; which, due to my own negligence were not as 'up-to-date' as they should have been. I hope this is the correction of the last issue.

If you find any issue with my Applications please contact me personally and allow me time to correct or adjust the issue. If a remedy cannot be found within 1 day or if you just want your money back I will gladly refund your entire purchase price.

Recently, comments have shown up stating my apps need internet connection to work or that the APPs are a waste of money. They even go so far as to imply that I have with-held a refund. It is not true! While the comments look legitimate, they are not left by real consumers. I am a full-time professor, and I am not trying to “scam” anyone or force my Apps on anyone. Furthermore; ALL Authentication of APPs sold by Android Market is done by Android Market. There is no Developer Authentication! Android Market has complete control! I am trying to provide an alternative to spending $125.00+ for a handheld graphing calculator. I do have a refund policy: If for ANY REASON you are unhappy with my app I will gladly request a full refund from Android Market and refund your money!
