Step-by-step explanation:

Hey what is cosec

Answer 2

Answer:

-7cot7xcosec7x

Step-by-step explanation:

$\frac{d}{dx}$cosec7x

=$\frac{d}{dx}$$($$\frac{cosec7x}{7x}$$)$X$\frac{d}{dx}(\frac{7x}{x})$                (applying chain rule)

=(-$cot7x$X$cosec7x$)X($7$)            (∵$\frac{d}{dx}cosecx=-cotxcosecx$)

=$-7cot7xcosec7x$
