SOLUTION: Prove the following: a) CosA/SecA = CotA b) SinA/1-CosA = CscA (1+CosA) Thank you :)

Question 1012121: Prove the following:
a) CosA/SecA = CotA

b) SinA/1-CosA = CscA (1+CosA)

Thank you :)

Prove the following:
a) CosA/SecA = CotA
Multiply thru by cos
cos = cos^2/sin
Not an identity.
======================
b) SinA/1-CosA = CscA (1+CosA)
If you mean SinA/(1-CosA) = CscA (1+CosA)
Multiply by 1-cos
sin = csc*(1-cos^2)
Multiply by sine
sin^2 = 1 - cos^2
