extreme sin^2(θ)

extreme points

sin^{2} (θ)

Minimum (πn, 0), Maximum (\frac{π}{2} + πn, 1)

Solution steps

Find the critical points:

θ = πn, θ = \frac{π}{2} + πn

Domain of

sin^{2} (θ) : - \infty < θ < \infty

Find intervals:

Increasing

: πn < θ < \frac{π}{2} + πn,

Decreasing

: \frac{π}{2} + πn < θ < π + πn

Plug the extreme point

x = πn

into

sin^{2} (θ) \Rightarrow y = 0

Minimum (πn, 0)

Plug the extreme point

x = \frac{π}{2} + πn

into

sin^{2} (θ) \Rightarrow y = 1

Maximum (\frac{π}{2} + πn, 1)

Minimum (πn, 0), Maximum (\frac{π}{2} + πn, 1)

f (x) = \frac{x + 3}{x ( x + 5 )}

f (x) = \frac{x ^{3} - 1}{x ^{2} - 4 x + 3}

f (x) = x + 2 y = 4

f (x) = 5 ((\frac{( 4 )}{7})^{x} - 2)

x^{2} - 6 x - 7
