RE: Attached integral calculator cannot solve
You just have to realise that
'∫(2,2,(X^3*COS(X/2)+1/2)*√(4X^2),X)' = '∫(2,2,X^3*COS(X/2)*√(4X^2),X)' + '∫(2,2,1/2*√(4X^2),X)' The first part is an odd function, so the integral is zero, and we are left with the easy second part. Cheers, Werner 41CV†,42S,48GX,49G,DM42,DM41X,17BII,15CE,DM15L,12C,16CE
