D and E Q3) a) What is the power of the signal below?x(t) = 5 cos(10t + π/2)TIP: use the trigonometric identity: cos²(a) = (1 + cos(2a))b) Does the power of x(t) change if you change the angular frequency from 10 rad/s to 20rad/s? Y/Nc) Does the power of x(t) change if you change the phase from π/2 to л/3 ? Y/Nd) What is the power of the signal below?x(t) = 5 cos(10t + π/2) + 3 cos(20t + π/3)TIP: use the trigonometric identity: cos(a)*cos(b) = ½ * [ cos(a-b) + cos(a+b) ]e) TRUE or FALSE: Power of a sum of sinusoids is equal to the sum of the powers of the sinusoids.
