Graphing Calculator 4 for Android

Remember the graphing calculator that used to be bundled with OS 9? This is it. If you enjoyed the original, you'll enjoy this. Unfortunately, despite being updated as recently as a month ago, there's still no support for Retina displays, so parts of the app are conspicuously blurry on my screen. Surely this is an easy fix, yeah?

For some reason I thought I would have been able to do more with this app, but it is extremely limited. The graphing app that came preinstalled on my computer is superior. I would really like a refund.

I love using this for visualizing surfaces, Fourier series, complex functions, polar coordinates, fractals, implicit functions… pretty much anything can be done on here. Great for graduate school and visualizing stuff. However, you guys have got to fix some things: this app is very picky, far too picky. As one types something, it will autofill in undesired commands, like badly places parentheses when typing trigonometric functions. That is aggravating as all hell. Please, put a way in the app to turn that off. Also, this thing has a seizure when trying to integrate functions that are unbounded on a compact set, even if they are Lebesgue integrable. Or even just well-behaved integrals on unbounded domains. That is also aggravating because this thing has the capability to do some great integrals. Maybe you guys could put in an algorithm for handling Lebesgue integration?

i use this for college alegebra at BYUI. It is amazing what it can do. Just make sure you look at the help window on how to do things. Rather have this way more than a TI graphing calculater. Its way better. Also got a quick response from support to one of the questions I had.
