# How do you use the Fundamental Theorem of Calculus to find the derivative of #int (u^3) / (1+u^2) du# from 2-3x to 5?

##### 1 Answer

#### Explanation:

The following assumes you mean the derivative wrt

We start with the formal statement of the FTC, Part I:

If in fact

We can also play with the intervals ..... in summary

Gasp! With all that, we just need to process this:

Maybe you can further simplify that.
