Question 943941: please help me solve this problem
verify identities
cos^2(x) cos(x)
------ = ------ or cos^2(x) over 1-sin(X)= Cos(x) over sec(x)-tan(x)
1-sin(X) sec(x)-tan(x) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! verify identities
cos^2(x) cos(x)
------ = ------
1-sin(X) sec(x)-tan(x)
============================
(1-sin^2)/(1-sin) = cos/(1/cos - sin/cos)
-----
1+sin = cos/(1-sin)/cos
-----
1+sin = cos^2/(1-sin)
-----
1+sin = (1-sin^2)/(1-sin)
----
1+sin = 1+sin
