## Homework Statement

Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer values. If an answer does not exist, enter DNE.)

g(θ) = 28θ − 7 tan θ

## Homework Equations

The critical values of a function, f, are located where f'(c) = 0 or DNE.

## The Attempt at a Solution

g(θ) = 28θ − 7 tan θ

g'(θ) = 28 − 7 sec(θ)^2

0 = 4 - sec(θ)^2

4 = sec(θ)^2, when θ = ((6*n-1)*pi) / 3
