In Exercises 1 - 20 , find the exact value or state that it is undefined. $$ \sec \left(-\frac{5 \pi}{3}\right) $$

Use the Sum and Difference Identities to find the exact value. You may have need of the Quotient, Reciprocal or Even / Odd Identities as well. $$ \tan \left(375^{\circ}\right) $$

Graph one cycle of the given function. State the period of the function. \(y=\sec \left(x-\frac{\pi}{2}\right)\)

Graph the oriented angle in standard position. Classify each angle according to where its terminal side lies and then give two coterminal angles, one of which is positive and the other negative.. $$ \frac{5 \pi}{4} $$

Use the Sum and Difference Identities to find the exact value. You may have need of the Quotient, Reciprocal or Even / Odd Identities as well. $$ \cos \left(\frac{7 \pi}{12}\right) $$

Graph the oriented angle in standard position. Classify each angle according to where its terminal side lies and then give two coterminal angles, one of which is positive and the other negative.. $$ -\frac{\pi}{3} $$

Use the Sum and Difference Identities to find the exact value. You may have need of the Quotient, Reciprocal or Even / Odd Identities as well. $$ \sin \left(\frac{\pi}{12}\right) $$
