In this problem, give all the answers with FIVE decimal places! Let voltage be u(t) = 123.13 V sin(15.6 . t + 0.34876). (a) When does the voltage reach its' peak value for the first time after t = 0 s? (b) When does the voltage evaluate to zero for the first time after t = 0 s? (c) When does the voltage evaluate to u = 99.61 V for the first time after t = 0 s? t (d) When does the voltage evaluate to u = 99.61 V for the second time after t = 0 s? t : (e) When does the voltage evaluate to u = 99.61 V for the third time after t = 0 s? t
