Verify the Identity (sec(x)^2-tan(x)^2+tan(x))/(sec(x))=sin(x)+cos(x)
Start on the left side.
Apply pythagorean identity.
Write in sines and cosines using the quotient identity.
Apply the reciprocal identity to .
Multiply the numerator by the reciprocal of the denominator.
Apply the distributive property.
Multiply by .
Cancel the common factor of .
Rewrite as .
Because the two sides have been shown to be equivalent, the equation is an identity.
is an identity
