Question

Find the amplitude, phase, period, and frequency of the sinusoid V(t) = 12 cos(50t + 10 degrees).
Options
A A=12V, theta=10deg, T=0.1257s, f=7.958Hz
Correct Answer
B A=12V, theta=10deg, T=1.0257s, f=7958Hz
C A=12V, theta=10deg, T=0.1275s, f=7.985Hz
D A=12V, theta=10deg, T=0.1257s, f=7.985Hz
Correct Answer

Option A is the correct answer.

Detailed Explanation

omega=50 rad/s. T=2*pi/50=0.1257s. f=1/T=7.958Hz.

Hint

omega=50 rad/s.
