Things are still pretty messy, and the “∫cos(x) ex dx” part of the equation still has two functions multiplied together.Sometimes, when you use the integrate by parts formula and things look just as complicated as they did before, with two functions multiplied together, it can help to ...
Integration by parts, like substitution, requires a little bit of finesse and trial by error. The whole point of integration by parts is to take a large picture and separate it into more manageable chunks. We're taking the big, ugly integral of udv and separating it into uv (which ...
How to integrate ...x sin(x) ∫ x sinx dxThis uses integration by parts:uv - ∫ v duu = xdu = dxdv = sinxv = -cosxNow plug in:-xcosx + ∫ cosx dx-xcosx + sinx + CRT..答案都给我了 但我看不懂 .. 答案 这个是让你用分部积分计算∫ x sinx dx因为分部积分公式∫ u dv = ...
