Quick Calculus, a simple yet powerful tool for computing the derivatives, integrals, Taylor series, and limits of functions. KeatsSoft Quick Calculus helps you quickly find the solutions of calculus problems, freeing you from the tedious manipulation of mathematical equations. Through an intuitive graphical interface, Quick Calculus helps you find the answers in a few seconds. You can get the following symbolic or numerical results: 1. the first and successive derivatives of functions, 2. the definite and indefinite integrals of functions, 3. any order of Taylor series of functions, 4. the left and right limits of functions, 5. the limit and integration of value at infinity.

Quick Calculus is divided into four modules of similar graphical user interface. They are:

1. Differentiation
2. Integration
3. Taylor Series
4. Limit

The special symbols and supported functions are given in Symbols, Operators, and Functions. In addition, we supply some relevant mathematical formula for quick reference, please see Useful Mathematical Formula.
