Verify that the equation is an identity. tan 4x - secºx = -2 tan ?x-1 To verify the identity, start with the more complicated side and transform it to look like the other side. Choose each step. Factor the tan "x-secºx = »(tan?x + sec sec?x) difference of two squares tan?X + 2 tan x sec X + sec? = (Тут Apply a Pythagorean identity. tan?X + sec? tan?x-2 tan x sec X + sec?x Choose an identity, ar fy....
