Chapter 26, Problem 19P

Perform the indicated operations on the following nonsinusoidal waveforms:

1. $\left[{\text{60 + 70sin ωt + 20sin (2ωt + 90}}^{\text{0}}{\text{) + 10sin (3ωt + 60}}^{\text{o}}\text{)}\right]\text{] + 20 + 30sin ωt - 20cos 2ωt + 5cos 3ωt]}$
2. ${\text{[20 + 60sin α + 10sin (2α - 180}}^{\text{o}}{\text{) + 5cos (3α + 90}}^{\text{o}}{\text{)] - [5 - 10sin α + 4sin (3α - 30}}^{\text{o}}\text{)]}$
