The only things specified are time, t, frequency, 25 w/(2 Pi) and magnitude of 3 with no units. Generally there will be a t < 0 in which the result would be zero for any real waveform, but there a theoretical exceptions.

can u do the calculation ?

kenljw · Answer

The mean value is zero
The rms value is 3/sqrt(2)
Still no units or t where waveform goes to zero
