Description:

Graph equations in two, three, and four dimensions. Graph explicit functions, implicit relations, parametric curves and surfaces, inequalities, points, vectors, contour plots, density plots, color maps, vector fields, ordinary differential equations, surfaces of revolution, polytopes, coordinate transformations, conformal maps and complex-valued curves, surfaces, and ODEs. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically. Create mathematical movies and web pages.

Worth the money - 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.

Useful but aggravating - 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?
