b. (cos{θ})/(1+sin{θ})-tan{θ}=sec{θ}
c. (cos2x+sin^2{x})/(cos{x})=cos{x}
d. csc{2A} - cot{2A} = tan{A} Answer by tommyt3rd(5050) (Show Source):
You can put this solution on YOUR website! a) not an identity - try
b) also not an identity - see the graph
It seems that your instructions are misleading...please repost with a clear and complete question :)
