Question

Sin theta/1+cos theta​

Answer 1

Step-by-step explanation:

sin○/(1+cos○)=(2sin○/2.cos○/2)/(2cos○/2.Cos ○/2)

= (2sin○/2)/(2cos○/2)

= tan○/2

Answer 2

Answer:

sintheta /1 +cos theta

divinding and multiplying (1-cos theta) on fraction

then the equation

is

sin theta (1-cos theta)/1-coss square theta

since the 1- cos squre theta is equal to sin squre theta

then you can solve ...
