A batted baseball leaves the bat at an angle of \(\theta\) with the horizontal and an initial velocity of \(v_{0}=100\) feet per second. The ball is caught by an outfielder 300 feet from home plate (see figure). Find \(\theta\) if the range \(r\) of a projectile is given by \(r=\frac{1}{32} v_{0}^{2} \sin 2 \theta\).
Use a graphing utility to approximate the solutions (to three decimal places) of the equation in the given interval. $$3 \tan ^{2} x+5 \tan x-4=0, \quad\left[-\frac{\pi}{2}, \frac{\pi}{2}\right]$$
Solve the multiple-angle equation. $$\cos 2 x=\frac{1}{2}$$
Use inverse functions where needed to find all solutions of the equation in the interval \([0,2 \pi)\). $$\sec ^{2} x+2 \sec x-8=0$$
Use inverse functions where needed to find all solutions of the equation in the interval \([0,2 \pi)\). $$\tan ^{2} x-6 \tan x+5=0$$
