GraphCalc Pro

This calculator’s advanced features give it a leg up on many similar applications. The interface doesn’t simulate a real calculator, but since GraphCalc has a relatively large number of features and settings, we can understand why the developer needed the extra space. Unlike many common calculators, this program lets you draw detailed graphs in 2D and 3D, as well as analyze functions. The last feature includes such tools as finding an intersection of two functions and drawing the tangent line. If you need to work with statistical or probability equations, you can add the corresponding buttons to the main window. To enlarge the functionality, you can create scripts using if and while operators. You’ll also find presets for determining such equations as volume and surface area of various shapes. We think GraphCalc makes a fine find for anyone who routinely works with complex mathematics.
