# Polynomial approximation

- Author:
- Juan Carlos Ponce Campuzano

Approximation of functions using:

- Legendre and Chebyshev polynomials on the interval [-1,1].
- Cosine and Sine series on the interval [0,pi].

- Change the function f(x).
- Select an option to approximate: Legendre, Chebyshev, Cosine or Sine.
- Drag slider to approximate.

**WRONG**, since the first three coefficients are zero by default in the simulation. Enter the first three coefficients to calculate the**CORRECT**approximation.
