Find the exact values of all the trigonometric functions for the giocn calues of \(t .\) If a certain value is undefined, state sa Do not use a calculator. $$t=5 \pi$$

Use a calculator to evaluate each trigonometric function. Make sure that the calculator is in \(R A D I A N\) mode. $$\cos ^{-1} 0.125$$

Find two angles that are coterminal with it. $$-55^{\circ}$$

Use your knowledge of horizontal stretches and compressions to graph at least two cycles of the given functions. $$f(x)=\sin \left(\frac{1}{2} x\right)$$

Use the given value of a trigonometric function of \(\theta\) to find the values of the other five trigonometric functions. Assume \(\theta\) is an acute angle. $$\csc \theta=2$$
