## Homework Statement

Differentiate f = arctan(u/v) with respect to u

## The Attempt at a Solution

Using the chain rule

f

_{u}= (1/(1 + (u/v)

^{2})) * 1/v = 1/(v + u

^{2}/v)

The solutions manual says v/(u

^{2}+ v

^{2})

What is my mistake?

Multiply the top and bottom of your answer by "v" and see what you get
