App Description
A powerful scientific and graphing calculator with matrices and complex numbers.
This free scientific calculator offers a number of useful features allowing you to carry out advanced calculations. Its simple and intuitive design makes it a pleasure to use. The calculator has all the functions that would be expected of a scientific calculator and a number of more advanced features too, including complex numbers and matrices.
The super fast algorithms allow the scrolling and zooming of 2D and 3D graphs in real time, using the touch sensitive screen.
Graph implicit equations in 2 and 3 dimensions. e.g. x²+y²+z²=5².
Graph inequalities in 2 dimensions. e.g. 2x+5y<20.
Graph functions of a complex variable.
Display up to 5 graphs on the same screen.
Active analysis of functions, for better graphing of 2D functions with singularity points. e.g. y=tan(x) or y=1/x.
Intersections on 2D graphs.
The calculator is customizable allowing you to change the colors of the screen, background and all the individual buttons, allowing you to personalize its appearance.
A fully ad free version of this app is also available.
