For the second one, another option besides logarithmic differentiation is exponential differentiation:
Now use the exponential, chain and product rules to find the derivative.
Differentiate: h(t)= ln((t^2+1)/(t+1))
I'm having some trouble with this one. Not sure if I am doing too much work for it.
Also this one: y= x^x^2
Do I have to use logarithmic differentiaton for the second?
