It was computed as if there was no a half wave rectifier.
To solve this question you don't need to going on complicated expressions. In a half wave rectifier Vdc = Vp/pi.
P=Vdc^2/R thus you have Vdc^2=30*24 =720.
Vdc=26.83 and Vp = 84.29.
As the frequency is 50 Hz you have: 84.29 *sin(100*pi*t)
No exactly, since the integration is done from 0 to Π, the answer
is correct. For a full sine Vrms=Vpk*0.707 and for a half wave
rectified sine Vrms = Vpk*0.5. (If I am not mistaken)
So, I think the answer is correct.
