Question 1016252: verify the trigonometric identity by rewriting the expression on one side of the identity in equivalent forms until it is identical to the expression on the other side.

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

You can put this solution on YOUR website!
1 + sin x = cos x/sec x - tan x
------------
1 + sin x = cos^2 x - tan x
1 + sin x = cos^2 x - tan x = cos^2 - sin/cos
1 + sin x = cos^2 x - tan x = 1 - sin^2 - sin/cos = sin*(sin - 1/cos)
1 + sin x = sin*(sin - 1/cos)
@ x = 0, 1 + 0 =? 0*(0 - 1)
Not an identity.
