Re: Absolute value of Sine Wave
Charlie,
This was a tricky question that I had encountered. Now I can see that the reason for the question is to account for the effect of the absolute sign on the period. I along with others forgot or missed this sign and didn't account for it and came up with 1/60 as opposed to 1/120 that you correctly calculated. It is mathematical question but it is also an engineering one since it represents a full wave rectification of the sine wave. if you plot it you will see a rectified full wave.
