Verify that the equation is an identity. tan x-secx=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 4x=( (tan 2x + secx) Factor the difference of two squares. tan2x-2 tan x secx+ sec2x tan2x+2 tanx secx+ secx n2x - secx tan tan 2x + secx
