USE MATLAB, PLEASE!

This data file containing three variables

y, y_noise, and h.

y is a function sampled at h = 0.01 time intervals.

y_noise is a noisy curruption of it.

Take numerical derivatives of y and y_noise in MATLAB.

Plot them together.

y = cos(t)

y_noise = cos(t) + (a small noise term, can you also explain what a noise term is)

h = 0.01
