Question

can any body please solve this problem please ​

Answer 1

$- \frac{3 \sin(3x) }{ \sqrt{1 - { \cos }^{2} (3x)} }$

Hmmm...

Answer 2

Answer:

0

Solution:

d/dx(sin^-1)(cos3x)

First find the derivative of sin^-1

d/dx(sin^-1) = 0

Next, find the derivative of cos 3x

d/dx(cos (3x))

= -sin(3x) d/dx(3x)

= -3sin(3x)

Then combine

0 * -3sin(3x) = 0

Hope this will be helpful to you.
