Features:
- solve equations
- plot cartesian functions with intersections
- plot polar- and spherical functions
- plot parametrical equations
- plot complex functions (draw real part & imaginary part)
- plot vector fields in 2D and 3D (full version)
- plot implicit equations F(x,y,z) (full version)
- complex numbers
- vectors & matrices
- truth- and value tables
- trigonometrical and hyperbolic functions
- piecewise-defined functions
- logarithmic functions
- logical & binary operators
- definite integral
- n-th derivations
- statistical functions
- physical and mathematical constants with units
- animate variables
- share content with other apps
- and a lot more...

The app is easy to use and helps students and engineers to visualize and solve their mathematical equations.
