Question

Help me with this …. It’s easy?

Answer 1

Given;

secθ/tanθ

Now,

Rewrite tan(θ) in terms of sines and cosines.

secθ ÷ sinθ/cosθ

Rewrite secθ in terms of sines and cosines.

1/cosθ ÷ sinθ/cosθ

Multiply by the reciprocal of the fraction to divide by

sinθ/cosθ

i.e.,

1/cosθ × cosθ/sinθ = 1/sinθ

Convert from 1/sinθ to csc(θ)

csc(θ).

Hence Proved!!
