Question

If cotV =40/9 , find the values of cosecV​

Answer 1

so,cotV=40/9

cosecV=41/9

it is correct answer

Answer 2

Answer:

GIVEN=>

cotV =40/9

---------------

find =>

cosecV=?

---------------------

solution=>

WE know that

$\huge\color{red}{1+cot^2=cosec^2x}$

where

x=V

Step-by-step explanation:

$= > \csc {}^{2} (v) = 1 + ( \frac{40}{9} ) {}^{2} \\ \\ = > \ \csc (v) = \sqrt{1 + \frac{1600}{81} } \\ \\ = > \csc(v) = \sqrt{ \frac{81 + 1600}{81} } \\ \\ = > \csc(v) = \sqrt{ \frac{1681}{81} } \\ \\ = > \csc(v) = {41/9}$
