Question H:

Let’s keep using the AM-radio style signal from Question G: f(x) = sin(12x) * sin(x) on [0,2*pi].

It’s okay to use Wolfram Alpha or Desmos to do the following integrals.

i)

Integral	Numeric result
(1/pi)integral of f(x)cos(1x) dx from 0 to 2pi
(1/pi)integral of f(x)cos(2x) dx from 0 to 2pi
Etc., with cos(3x)
...cos(4x)...
...cos(5x)...
...cos(6x)...
...cos(7x)...
...cos(8x)...
...cos(9x)...
...cos(10x)...
...cos(11x)...
...cos(12x)...
...cos(13x)...
...cos(14x)...

ii) What do you get if you graph 0.5*cos(11x)+-0.5*cos(13x) ?
