Question

The third harmonic of a sound wave is given by;

?1 = 40 sin(4?) ?2 =?cos(4?)

The signal processor adds the signals to form a third signal, which must be described as a distinct signal

in the following form;
Use a compound angle identity to determine the value of A (the amplitude of ?2).

?? =50sin(4?+?)

Ensure that you have your calculator in Radians (RAD) mode when determining your answer.

Use graphical software to plot/model the inputs and output of the signal processor. How do you think graphical methods of sine wave combination compare with analytical methods?

I have the solution for this but I am unsure how to plot the inputs and outputs of the signal processor. Can I see the graph showing this and the answer as to how this method compares to analytical methods.
