L.H.S,
→cos²A/sinA+sinA
→cos²A+sin²A/sinA. [sin²A+cos²A=1]
→1/sinA
→cosecA... [1/sinA=cosecA]
L.H.S=R.H.S

Answer:
Cos^2 sin theta+ sin theta =
Cos^2theta/sin theta+ sin theta *sin theta=
Cos^2 theta+sin^2theta/sin theta
=1/sin theta( because sin square theta + cos square theta is equals to 1)
=cosec theta.
Here is your answer.Mark it as brainliest
