Im learning to do integration using the substitution method.
My problem is:
(4,0) (the 4 and 0 are at the top and bottom of the integration sign (the upper and lower bound)
using the substitution method.
i let u = 1+2x
so du = 2dx (?)
then i tried substituting back into the equation:
dx = 1/2du
Any help would be appreciated.. i dont know if this is right.
