Question

How do you express cosθ csc θ in terms of tanθ?

Answer 1

`color(blue)(=> 1 / tan theta`

Explanation:

`cos theta csc theta`

`=> cos theta * (1 / sin theta), color(brown)(" since " csc theta = 1/ sin theta`

`=>cos theta / sin theta`

`=> 1 / (sin theta / cos theta)`

`color(blue)(=> 1 / tan theta, color(maroon)(" since " sin theta / cos theta = sin theta`
