Hi Thank you very much for your reply. I have just twigged my error in my calculation - I've literally been at it 3 hours! I don't believe I have missed a term the error was when dividing by 200pi on the calculator. I was dividing [sin(200pi(0.005)+0.4)] by 200pi not by (200pi). Glad that is...

Hi, I have an example in my studies as follows: If v = 200sin(100pi*t + 0.2) then evaluate Integral of v^2 dt between limits of 0.005 and 0. I have integrated it and used the double compound angle formula sin^2 A=1-cos2A and come up with the following as per the solution to the example in the...

Thank you!
