Csc α 0 and tan α 0
WebIf \(\cos α = \frac{4}{5}\) and tan α < 0, evaluate a) sin α and b) cot α. Solution. Because cosine > 0 and tangent < 0, angle α is in quadrant IV and the signs of the trigonometric functions should be for that quadrant (see Lesson 4-05). An identity relating cos α and sin α is a Pythagorean Identity. WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations.

WebQuestion: Suppose an angle 𝛼 is drawn in standard position. In each case, use the information to determine what quadrant 𝛼 is in. (An angle is in standard position if it is drawn on the xy-plane with its vertex at the origin and its initial side is on the positive x-axis.) (a) csc(𝛼) < 0 and tan(𝛼) > 0. (Select all that apply.) WebApr 14, 2015 · Explanation: cosA = 5 13. sin2A = 1 − cos2a = 1 − 25 169 = 144 169. sinA = ± 12 13. There are 2 opposite values of sin A, because, when cos A = 5 13, the arc (angle) A could be either in Quadrant 1 or in Quadrant 4. There are also 2 opposite values for tan A. tanA = sinA cosA = ± ( 12 13)(13 5) = ± 12 5. Answer link.
