Question

[1-cos A ÷sin A] is equal to
​

Answer 1

Answer:

tanA/2

Step-by-step explanation:

(1-cosA)/sinA

=(1–1+2sin^2A/2)/2.sinA/2.cosA/2.

=(2sin^2A/2)/(2sinA/2.cosA/2.)

=(sinA/2)/(cosA/2)

= tanA/2

Answer 2

$= 1 - \cos(a) \div \sin(a) \\ = 1 - \frac{ \cos(a) }{ \sin(a) } \\ = 1 - \cot(a)$
