Verify the identity. 1- sin x (secx- tan x) = 1 + sin x To verify the identity, start with the more complicated side and transform it to look like the other side. Choose th correct transformations and transform the expression at each step. (secx- tan x) (Do not simplify.) Factor out the greatest common factor. Apply a Pythagorean identity inside parentheses. Apply the appropriate even-odd identity inside parentheses.
