Answer 2

Answer:

-3 cosec 3x cot 3x

Step-by-step explanation:

Here, the given equation is

Cosec 3x

and we find the derivative of cosec 3x

Now, differentiate the cosex 3x with respect to x, we get

$\frac{d}{dx} cosec3x$

the differentiation of cosec x is -cosec x cot x

So, the differentiation of cosec 3x is

= - cosec 3x cot 3x (3)

here 3 is the differentiation of 3x

so the answer will be

= -3 cosec 3x cot 3x
