critical 14cos(θ)+7sin^2(θ)

critical points

14 cos (θ) + 7 sin^{2} (θ)

θ = 2 πn, θ = π + 2 πn

Solution steps

14 cos (θ) + 7 sin^{2} (θ)

Find where

f^{'} (θ)

is equal to zero or undefined

θ = 2 πn, θ = π + 2 πn

Identify critical points not in

f (θ)

domain

Domain of

14 cos (θ) + 7 sin^{2} (θ) : - \infty < θ < \infty

All critical points are in domain

θ = 2 πn, θ = π + 2 πn
