WitrynaJust by looking at the definition of sec ( x), one can clearly see that. sec ( x) = 1 cos ( x) But don't just take my word for it. Your equation itself will tell you if it's right or wrong. − sec ( x) = 1 cos ( x) − 1 cos ( x) = 1 cos ( x) − 1 = 1 False. Witryna(1 - secx)/(1 + secx) = (cosx - 1)(cosx + 1), verify the identity.
