Magazine Problem 21
Given that \(k\) is any integer, list all of the possible values for \(x\) that are in the specified interval. $$\frac{\pi}{2}+k \cdot \pi,-3 \pi \leqslant x \leqslant 3 \pi$$
Problem 21
The measure of an angle in standard position is given. Find two angles - one positive and one negative - that are coterminal with the given angle. If no units are given, assume the angle is in radian measure. $$175^{\circ}$$
Problem 21
Use identities to find an equivalent expression involving only sines and cosines, and then simplify it. $$\sec \theta+\sin \theta$$
Problem 21
Rewrite the expression as an algebraic expression in terms of \(x\). $$\cos (\arcsin x)$$
Problem 21
State the exact value of the sine, cosine and tangent of the given real number. $$-\frac{3 \pi}{4}$$
Problem 22
