Hi,

Im learning to do integration using the substitution method.

My problem is:

Integrate

x/[root(1+2x)]dx

(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

so..

Any help would be appreciated.. i dont know if this is right.
