In which quadrant is csc negative
WebFor an angle in the second quadrant the point P has negative x coordinate and positive y coordinate. Therefore: In Quadrant II, cos (θ) < 0, sin (θ) > 0 and tan (θ) < 0 (Sine positive). For an angle in the third quadrant the point P has negative x and y coordinates. WebThe cosine of a 2nd quadrant angle θ is the negative of the cosine of its corresponding acute angle, which is its supplement. In other words: The angle whose cosine is − x is the supplement of the angle whose cosine is x. arccos (− x) = π − arccos x. Example 3. Evaluate arccos (−½). Solution . We have seen: arccos ½ = .

Since `cos x = -1/2` and `x` is in the third quadrant, we know that `sin x` is negative. Using the identity `sin^2x + cos^2x = 1`, we can solve for `sin x`: `sin^2x + (-1/2)^2 = 1` `sin^2x = 3/4` `sin x = -sqrt(3)/2` raymond lylesWeb19 mrt. 2010 · In Quadrant II, is the value of cosecant positive or negative?
