* This is the professional version of my scientific calculator. It includes symbolic algebra and is completely ad-free.
This scientific calculator offers a number of useful functions that allow you to perform advanced calculations. Its simple and intuitive design makes it a pleasure to use. The calculator has all the features you would expect from a scientific calculator as well as a number of more advanced features, including complex numbers and matrices.
Super-fast algorithms allow scrolling and zooming of 2D and 3D graphs in real time, using the touch sensitive screen.
Draw implicit equations in 2 and 3 dimensions. for instance. x²+y²+z²=5².
Inequality graph in 2 dimensions. for instance. 2x+5a<20.
Graphic functions of a complex variable.
View up to 5 graphs on the same screen.
Active function analysis, for better graphing of 2D functions with singular points. for instance. y=tan(x) or y=1/x.
Intersections on 2D graphs.
The calculator is customizable allowing you to change the colors of the screen, the background and all the individual buttons, allowing you to customize its appearance.
