    Hi all,
    I have a sine wave with a f of 2.2khz and rms value of 25v. The cycle begins at 0 and I need to know the change in voltage from 0.12ms to .2ms. I calculated the period to be .45ms and the peak voltage is 35.35v but I am stuck after that.

    Any help would be greatly appreciated.

    If you can substitute angle for time, you may find that the sine of the angle will have to do with the voltage. For instance, given the period of the wave, what is the time to go from 0 to 90 degrees?
