Expert Answer

Step 1

The expression of voltage (E) as a function of time is given below.

E = 1.3∙cos(100∙π∙t)

Step 2

If A is the amplitude, ω is the angular frequency. Then the general equation of the cosine wave function is given by:

Y(x) = A∙cos(ω∙t)

Step 3

Comparing the given equation with the general equati...
