HELP!!! trigonometric problems....?

Question

Can you please prove the ff. identities

the / stands for a fractionbar i just can't put one so I used a /

Q.#1:


1 + 1/
Cos A
/
2 - 1/
SIN A



Q.#2:


3 + 1/
SIN²A
/
1
/ A
SIN²

Well that's the problem my teacher gave me she didn't put any equality sign...

Answer 1

1+1/cosA/2-1/sinA
=[(1+cosA)/cosA)]/[(2sinA-1)/sinA]
=sinA(1+cosA)/cosA(2sinA-1)

2.(3+1/sin^2A)/(1/sin^2A)
=[(3sin^2A+1)/sin^2A]/(1/sin^2A)
=3sin^2A+1

Answer 2

u havent given the equality sign....what do we have to prove it equal to?
