The period is 2π. b The phase shift is c units to the left if c > 0. The The phase shift is c units to the right if c < 0. The The vertical shift is d units up if d > 0. The 0. The vertical shift is d units down if d < 0. The Asymptotes Asymptotes The secant function has asymptotes 2n + 1 b( x + c ) = ÷π , if n is an integer . 2 The cosecant function has asymptotes b( x + c) = nπ , if n is an integer .
