Csc α 0 and tan α 0
WebDec 3, 2024 · If csc(α) = 3, where 0 < α < π/2, and β is a Quadrant II angle with tan(β) = −7, find . cos(α+β) And there are others that I'm supposed to find, such as sin(α+β), but this is just the first question. 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.)

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.
