With reference to , is 24sqrt(2) the RMS value of the sine wave?
No, it is the peak value, which occurs when the value inside the parentheses is equal to 90 or pi/2 radians. This makes the value of the sin function equal to 1.
If I didn't know better I'd almost suspect you of trolling.
The RMS value is
Where is the peak value.
The RMS value is 24.
I would recommend that you go back to the definition of what rms voltage is (not some formula for it, but what it means, namely that the rms value of a waveform is equal to the voltage that a DC source would have that dissipated the same amount of average power in a purely resistive load). From that, you should be able to come up with the formula that thumb2 gives and, in the process, cement in your knowledge what rms voltage is and why rms stands for what it does.
