Which expression is equivalent to sec2xcot2x?

a.
sin2x

b.
csc2x

c.
`(1)/(cos^2x)`

d.
`(1)/(tan^2x)`

Option B is correct answer.

Step-by-step explanation:

We need to solve the expression sec2xcot2x.

We know sec x = 1/ cos x and cot x = 1/ tan x and tan x = sin x/cos x and 1/tanx = cosx /sinx

Since in question we 2x instead of x so, replacing x with 2x and Putting values:

So, Option B is correct answer.
