## Homework Statement

d/dx(sec(x)/1+tan(x)

Evaluate at x=∏/6

## Homework Equations

## The Attempt at a Solution

((1/cos(x))(1+tan(x))-(sec(x))(sin(x)/cos(x)))/(1+tan(x))^2

((1/cos(x))-(sec(x))(sin(x)/cos(x)))/(1+tan(x))

I used the quotient rule and reduced what I could. Have I done this right and can I go any further before evaluating? Thank you.
