Re: Specify the second derivative of the function
I can't read what's in the exponential. Could perhaps type it in?

Re: Specify the second derivative of the function
y=ln(1+x^2) +e^sqrt(x)

hoping this is the right way how to write it..

what you have done is correct so far. Just differentiate it again to get the second derivative.
