extreme f(x)=5sin(2x)+3

extreme points

f (x) = 5 sin (2 x) + 3

Maximum (\frac{π}{4} + πn, 8), Minimum (\frac{3 π}{4} + πn, - 2)

Solution steps

Find the critical points:

x = \frac{π}{4} + πn, x = \frac{3 π}{4} + πn

Domain of

5 sin (2 x) + 3 : - \infty < x < \infty

Find intervals:

Increasing

: πn \leq x < \frac{π}{4} + πn,

Decreasing

: \frac{π}{4} + πn < x < \frac{3 π}{4} + πn,

Increasing

: \frac{3 π}{4} + πn < x < π + πn

Plug the extreme point

x = \frac{π}{4} + πn

into

5 sin (2 x) + 3 \Rightarrow y = 8

Maximum (\frac{π}{4} + πn, 8)

Plug the extreme point

x = \frac{3 π}{4} + πn

into

5 sin (2 x) + 3 \Rightarrow y = - 2

Minimum (\frac{3 π}{4} + πn, - 2)

Maximum (\frac{π}{4} + πn, 8), Minimum (\frac{3 π}{4} + πn, - 2)

f (x, y) = e^{(x - y)} (x^{2} - 2 y^{2})

f (x, y) = y e^{x^{2} - 2 y^{2}}

\frac{x ^{3}}{3} - \frac{x ^{2}}{2} - 2 x + \frac{1}{3}

f (x, y) = x^{2} + x y - y^{2}

f (x, y) = x^{3} - y^{3} + 6 x y
