Nettet3. apr. 2024 · We start by integrating the function #sin^2(x)# so #int sin^2(x)dx = int 1/2 (1-cos(2x)) = 1/2 (x- sin(2x)/2) + C#. so then you do the original integral by party. you take: #u = x rArr dot u = 1# #dot v = sin^2x rArr v=1/2 (x- sin(2x)/2)# and we know that #int u dot v = uv - int dot u v# and so. #intxsin^2xdx = x/2(x-sin(2x)/2) - int 1/2 (x ...
