Evaluator

Evaluate your functions with this simple Evaluator implementaion

The purpose of this is to help one perform simple computations such as evaluating a function, differenting a function and integrating a function. Instead of explicitly defining the function, you can simply type the function as a string and evaluate it.

Example:

I can create a program that uses bisection method to find the root of the function f(x) = 4*cos(x) - 10. Instead of embedding the function in the code, the user can simply type the string, "4*cos(x) - 10" as input and get the desired output.

How to use

1. Import the Evaluator implementation into your project.
2. Call Evaluator.eval("f(x)", x) to evaluate f(x). It returns a double.

Examples: For f(x) = 4*cos(2x)*sin(x).

To find f(2): var value = Evaluator.eval("4*cos(2x)*sin(x)", 2); The Main.java has some driving code you can use to test the implementation

This project is in working progress

Currently, it can only evaluate linear functions, polynomials of power n,simple trig functions containing cos, sin and tan and exponential functions.
