Description

Visual Math 4D is a graphical calculator that allows you to visualize and solve your mathematical equations. It supports various types of equations, such as polar, spherical, parametric and implicit equations, which can be visualized and animated in 2D and 3D. You can also plot and animate vector fields in 2D and 3D.

Features:
- solve equations
- plot cartesian functions with intersections
- plot polar- and spherical functions
- plot parametric equations in 2D and 3D
- plot complex functions (draw real part & imaginary part)
- plot vector fields in 2D and 3D
- plot implicit equations in 2D and 3D
- plot contour maps ins 2D and 3D
- support for 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 (nPr, nCr, rand..)
- physical and mathematical constants with their units
- animate variables
- share content with other apps
- no network connection required
- and a lot more

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

Closes immediately after opening

I’m a university professor - thought this might help with classes. Unfortunately it shuts down just after opening. Hope this gets fixed. :(

Edit: reinstalling did work!! Thanks! Currently trying to figure out how to plot Poles and Zeros for DSP transfer functions (the 3-D kind on the unit circle as a kind of terrain plot). A DSP add-on package would be great!!!

Developer Response ,

Hello,
could you reinstall the app and restart it.
Which device and iOS-Version you are using?
The newest update needs iOS 11.

Great app, but some struggles

It’s an inspiring app, refreshing my math skills and learning new.
But the Delete button is nicely hidden - takes a while to find out how to correct typing mistakes.
How about a simple Backspace button in the Num block?

Developer Response ,

good idea. thx ;)
