WebMar 17, 2016 · Explanation: We have: ∫sin(2πt)dt. Substitute: u = 2πt ⇒ du = 2πdt. In order to have du in our integral expression, we must multiply the inside by 2π. However, we also must balance this by multiplying the outside by 1/2π. = 1 2π∫sin(2πt) ⋅ … Web0 Is for integration by parts ∫ u d v = u v − ∫ v d u applied 2 times: First, let u = t 2 and d v = sin β t d t; then d u = 2 t d t and v = − 1 β cos β t, so ∫ t 2 sin β t d t = − 1 β t 2 cos β t + ∫ …
