Use a graphing utility to approximate the solutions (to three decimal places) of the equation in the given interval. $$2 \sec ^{2} x+\tan x-6=0, \quad\left[-\frac{\pi}{2}, \frac{\pi}{2}\right]$$
Find the exact value of the expression. $$\cos 120^{\circ} \cos 30^{\circ}+\sin 120^{\circ} \sin 30^{\circ}$$
(a) use a graphing utility to graph the function and approximate the maximum and minimum points on the graph in the interval \([0,2 \pi),\) and (b) solve the trigonometric equation and demonstrate that its solutions are the \(x\) -coordinates of the maximum and minimum points of \(f .\) (Calculus is required to find the trigonometric equation.) Function $$f(x)=\sin x+\cos x$$ Trigonometric Equation $$\cos x-\sin x=0$$
