Verify that the equation is an identity. tan x-sec 4x-1-2 secx To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step. tan 4x-sec sec 4x=( tan x sec 12x-secx )(tan 2x + secx) Factor the difference of two squares. =(-1) (tan 2x+ sec 2x) Apply a Pythagorean identity. (Type an exact answer in simplified form.) Choose an identity, and use it to transform tan 2x. Then simplify. = 1-2 secx Apply a quotient identity. Apply a reciprocal identity.
