# Heat Equation Solution (partial Fourier series)

- Author:
- Albert Schueller

This is a partial Fourier series solution of the the one-dimensional heat equation with a zero left boundary and a Newton's Law of Cooling style right boundary condition. The sliders allow one to vary a few important physical parameters. Once the parameters are chosen, one can advance the solution in time with the slider.
The problem is based on Example 7.1 from Farlow's "Partial Differential Equations for Scientists and Engineers".

What is the effect of varying ?
