To differentiate arctan(x^2 + 1), you would use the chain rule. The derivative would be ((1 + (x^2 + 1)^2)) multiplied by the derivative of (x^2 + 1), which is (2x). So, the derivative of arctan(x^2 + 1) is (\frac{2x}{1 + (x^2 + 1)^2}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
