If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for <em>x</em> :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$

Why the following triangles are congruent!

dimaraw [331]

Answer:

Because the sides BO and MA are marked with one line through the middle, which means those sides are congruent, angle A and Angle O are marked with one line, the angles are congruent, and angles W and N are marked with two lines, which means they are congruent. Therefore the triangles are congruent

A squirrel runs across a road in 3 seconds. The road was more than 34 feet wide. Which inequality can be used to determine the s

kirill [66]

Answer:

Step-by-step explanation:

squirrel speed (r) x seconds (3) has to be more than 34 feet

3r is greater than 34

r is greater than 11.3

34 / 3 = 11.333

11.3 (squirrels speed) x 3 (seconds) = 33.9 feet

the squirrel can run faster than 11.3
