Need Help on Integration Problem

[TheLegendaryLoboSolo]

I have stared at this problem for quite a while, and I don't know how to approach it.

The problem is as follows:


Use the Second Fundamental Theorem of Calculus to find F'(x)
F(x)=∫[-1,x]√(t^4+1) dt


Any help on the process of obtaining the answer would be greatly appreciated.

Simply replace t with x.


\(\displaystyle \displaystyle\frac{d}{dx}\int_{a}^{x}f(t)dt=f(g(x))g'(x)\)
