Graphing Calculator 4 4+

Thank you for providing this much improved calculator over the default "Grapher" included with MacOS. The fact that it's free is very generous.

Please ensure that this amazing calculator has a path forward so that it can continue to be made available and improved for decades to come.

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.
