An equation of the form f(x) = g(x) is given. Use a graphing utility to graph y = f(x) and y = g(x) on the same screen on the interval [0, 27] (be sure to use radian mode). Make a conjecture as to whether the equation is an identity, a conditional equation, or a contradiction. a. sin 2x = 2 sin x b. cos 2x = 2cos?x- 1 secxsinx = 2 c. tanx
