5. 3 properties of trigonometric functions notes: sterling. Provide a generalization to each of the key terms listed in this section. What are the ratios for sine and cosine? b c. = |x | r y r y r b c = sin = c = cos = |x| r. A coterminal occurs when there are two angles that are in standard position if they both have the exact same terminal side. Thanks to the angle, which also means in this case, and the following where k can be expressed as any integer would be coterminal: = r y > 0 sec = c a = r x < 0 cot . Quadrant of sin cos tan csc sec cot . P ositive n egative n egative p ositive n egative n egative. When the acute angle formed is formed by both the terminal side of and the x-axis.
