Question

: Evaluate pls. found an answer for me..pls​

Answer 1

This question is solve by substitution method .

let cosecx=t

-cosecxcotx dx =dt

-cosecxcotx dx =-dt

then put the value in the question

Formula:

$\int {x}^{n} = \frac{ {x}^{n + 1} }{n + 1}$

$\frac{d( \csc(x)) }{dx} = - \csc(x) \cot(x)$

${ \csc }^{2} - { \cot}^{2} = 1$
