If cosec? + cot ? = 5 / 2 , then the value of tan? is

What is the simpliﬁed value of

(cosec A – sin

A)(sec A

(cosec A – sin

A)(sec A

The solution to dy/dx + y cot x = cosec x is

∫cosec(u)cot(u)du

If ƒ(x) = tan-1 and g(x) = tan(x), then (gof)(x) =

If a = tan60 tan 420 and B = cot660 cot 780

Cos

(90°+θ)sec(-θ)tan

(180°-θ)/sec

(360°-θ)sin

(180°+θ)

(90°+θ)sec(-θ)tan

(180°-θ)/sec

(360°-θ)sin

(180°+θ)

If sin? + cosec? = 2, then value of sin3? + cosec3? is

Assertion
