A graphing calculator is recommended.Use the Squeeze Theorem to show that lim x cos(9x) = 0.x10Illustrate by graphing the functions f(x) = -x, g(x) = x cos(9x), and h(x) = x on the same screen.Let f(x) = -x, g(x) = x cos(9x), and h(x) = x. Then ?s cos(9x) ? ? ?=2? x cos(9x) ? 2 ?Since lim x)= lim h(x) =X-0X10by the Squeeze Theorem we have lim g(x) =110
