Natural log problem
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

Let X be a topological space and let ${f_n}$ be a sequence of continuous functions from X to the real numbers. If f(x)= $\lim_{n->\infty} f_n(x)$ for all x in X, show that the set of points where
f is continuous is a $G_\delta$ set.
