When using the double integration method to solve for deflection, do you simplify the integral before integrating or do you just integrate it? When i tried it with simplifying and without simplifying, I get a different value for the constant which results in different answers. For example in the question attached, between L<x<2L, i got EIv''=-3PL+2Px-P(x-L). When I integrated this and solved for the constants I got C3=PL^2. When I simplified the moment equation to EIv''=Px-2PL, i got C3=PL^2/2. I am kinda confused here. Which way is correct? Thanks
