Question 1004854: Tanx+Cosx/(1+sinx)=secx
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! Tanx+Cosx/(1+sinx)=secx
----------------
You didn't say what you want to do.
To solve for x:
Tanx+Cosx/(1+sinx)=secx
Multiply thru by cos
sin + cos^2/(1+sin) = 1
sin + (1-sin^2)/(1+sin) = 1
sin + 1-sin + 1
1 = 1
-----------
True for all x, an identity.
x <> n*pi/2
