30 sec (2 - 15 x) tan (2 - 15 x)

Integrate the following with respect to x. 30sec(2-15x)tan(2-15x)

Integrate the following functions w.r.to 'x' . (i) sec^2""(x)/5 (ii) "cosec"(5x+3)cot(5x+3) (iii) sec (2-15x)tan(2-15x)

sec 2x - tan 2x=

(sec x sec y + tan x tan y) ^ (2) - (sec x tan y + tan x sec y) ^ (2) = 1 Prove it

Is (sec x + tan x + 1)(sec x - tan x - 1) - 2tan x = 0 an identity.

What is the simplified value of [ ((sec^(3)x - tan^(3)x ))/((sec x - tan x ))]-2 tan^(2)x - sec x tan x ?

log (sec 2x +tan 2 x)
