Gven the equation 1/sqrt(x) + 2log(A/rt(x) + b) with A and b constants.
i want to differentiate and then solve using newton raphson with a given initial value, any help would be largely appreciated!

Make a google search "Newton-Raphson & MATLAB".

i've looked over this before but because of the sqrt's it keeps leaving me with complex numbers.

Then substitute x=y^2 in your equation and thus solve 1/abs(y)+2log(A/rt(y^2)+b) =0 with A and b constants.
