QUESTION 1 The average power in the signal x (t) 4cos (10t - T/3) is 8 W True False QUESTION 2 The signal x (t) u ( + 5u (t-1) -2u (t-2) has an average power of 8W True False QUESTION 3 A signal that, within its amplitude range, is either 0 or 1, is a discrete-time signal. True False QUESTION 4 The signal x () sin (10T) + sin ... WebIt gets rid of the messy 2sin²x that makes your equation such a complicated thing to solve. First solve the identity for sin²x. cos²x + sin²x = 1. sin²x = 1 - cos²x. so, 2 ( sin²x ) = 2 (1 - cos²x) Now we plug that into your challenge problem: 2 (1 - cos²x) + cos x - 1 = 0. 2 - …
