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

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

∫cosec(u)cot(u)du

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

∫cosec(u)du

Cosec

(2040°) =

(2040°) =

Consider the scattering of neutrons by protons at very low e

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

∫cot(u)du
