A current i = 50sin 100πt mA flows in an electrical circuit. Determine, using integral calculus, its
a) Mean Value
b) RMS Value
each correct to 2 decimal places over the range t = 0 to t = 10 ms
I need to do this two way so I was thinking of using the trapezoidal rule and the Simpson's rule but I'm not sure how to.
Thank you for your help
