Question

d/dx cot(sec x+tan x) the result should be in the simplest form.​

Answer 1

= -cosec2((sec x + tan x) sec x. tan x+sec2x

Step-by-step explanation:

y=cot(sec x + tan x)

duff. w. r. t. x

dy/dx=d/dx cot(sec x + tan x)

-cosec2(sec x + tan x) d/dx(sec x + tan x)

= -cosec2((sec x + tan x) sec x. tan x+sec2x
