I meant that the derivitive of sqroot(x-3)=1/2sqroot(x-3)

Hi, I have to find the integral of 1/square root(x-3)dx this is what i did let u=sqr root(x-3) du=1/2*square root(x-3)dx dx=2*square root(x-3)du the integral of 1/square root(x-3)dx= 2*square root(x-3)(1/u)du ..ok now what i did is plug back u= square root of(x-3) in the denom...
