WebLet's say we start at theta is equal to zero. What is sine of theta gonna be? Well, when the angle is zero we intersect the unit circle right over there. The Y coordinate of this is still zero. This is the point, this is the point one comma zero. The Y coordinate is zero, so sine of theta is zero. We could say sine of zero is equal to zero. WebCalculus. Evaluate csc (0) csc(0) csc ( 0) Rewrite csc(0) csc ( 0) in terms of sines and cosines. 1 sin(0) 1 sin ( 0) The exact value of sin(0) sin ( 0) is 0 0. 1 0 1 0. The …

csc theta = -2, tan theta greater than 0 - YouTube

WebMay 28, 2016 · Cosine is positive in the same quadrants. Sine correlates with values of y. Values of y are negative in Quadrant III and Quadrant IV. Sine is negative in the same … WebMay 20, 2024 · 5 (15) Adaptive Math and Physics Tutor. About this tutor ›. If csc (θ) < 0, then sin (θ) < 0 because csc and sin are simply multiplicative inverses. If sec (θ) > 0, then cos (θ) > 0 because sec and cos are simply multiplicative inverses. Thus, θ must be in quadrant 4. Upvote • 0 Downvote. WebFor an angle in the first quadrant the point P has positive x and y coordinates. Therefore: In Quadrant I, cos(θ) > 0, sin(θ) > 0 and tan(θ) > 0 (All positive). For 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). 風邪 ぶどう膜炎
