An/a ______________ is formed by the rotation of a ray about the origin from an initial position to a terminal position. 3. An angle with its vertex at the origin and its initial side on the positive x-axis is said to be in _____________________________________. 4. Give the definition of each of the following using x, y, and r: a). sin 0 = ________ d) sec 0 = ________ b) cos 0 = ________ e) csc 0 = ________ c) tan 0 = ________ f) cot 0 = ________ 5. sin 0 is positive in quadrants _______ and ________. 6. cos 0 is positive in quadrants _______ and ________. 7.
