Mark the correct alternative in the following:
If , then sec x − tan x is equal to

⇒ sec x – tan x

⇒ -2x

∴ the value of sec x – tan x = -2x, 1/2x.

If x = sin¹⁴x + cos²⁰ x, then write the smallest interval in which the value of x lie.

If 3 sin x + 5 cos x = 5, then write the value of 5 sin x − 3 cos x.

Mark the correct alternative in the following:

If , then sec x + tan x =
