WebWhat matters here is at some point between zero and infinity we are going to end up in a situation where n=n, or, in other words, at some point between 0 and infinity the number paired with t equals the n that will cause the integral to be of cos^2 (nt) and this will always happen but only once. Therefore the answer will always be pi. WebMultiply both sides by 30: d = 0.6293… x 30 d = 18.88 to 2 decimal places.
