can someone help me to find the derivative of this function?? y=ln(x+(x^2+a^2)^1/2) I'm not getting the answer 1/(x^2+a^2) from my textbook thanks

yeah sorry i missed the sqrt...should be 1/(x^2+a^2)^1/2 ok I already got to that point but could not simplify any further??
LOOK again at the factors in the numerator and denominator ...
ooohh okay I can see it now...I can cancel the common factors thanks a lot I was blind...lol
