# Prove the trig identities

3, 9 and 7. Use the above numbers to prove only three of these trig identities.

sin x/ 1 + cos x = 1 - cos x/sin x

1/ 1 + Cos x = csc^2 x - cot x/sinx x

-sin x - cos x cot x= - csc x

1 + tan x/ 1 + cot x = tan x

What is meant by "the above numbers?" Also, please write out the equations a bit more clearly (eg: using parentheses, etc.)

I did all 4 of them. Take the proofs and go. The directions don't make sense
