An easy to use, intuitive program to study functions of one variable in a defined interval to find roots, maxima and minima, integral, derivatives, graph. You may predefine constants and specify the error bound for the results. It can explore intervals to search for solutions. Handles trigonometric and hyperbolic functions among others. Results can be saved or printed. Includes a help file with instructions, example and methodology.
Our Review: Functions is a simple yet effective program for plotting mathematical equations. It covers a wide range of functions including finding roots, maximum and minimum points, y-value at a point, 1st and 2nd derivatives, all the way up to the 9th derivative, and more. Graphs can be sent straight to the printer or saved for later use. Good help files are available covering the use of the program and terminology. A good resource for students studying Calculus.
