For the rule integral sign 1/x dx = ln lxl . does it only apply for 1/x? I mean does integral sign 1/2x dx = ln l2xl ?
Also
The problem is:
integral sign [-3e^(-x) + 2x - (e^(0.5x))/2] dx
Is this correct:
integral sign [-3e^(-x) + 2x - (e^(0.5x))/2] dx
= -3 x -e^(-x) + 2 x (1/2) x^2 - (1/2)(1/0.5)(e^(.5x)) + C
=3(e^(-x))+x^2-(e^(.5x)) + C
