For which angle θ is cos θ −1 270°

Webcsc(θ) = − √ 5 1 sin(θ) = − √ 5 1 = − √ 5·sin(θ) or sin(θ) = − 1 √ 5 This tells us that θ must be in quadrant III or IV. We are also given cos(θ) < 0, so θ must be in quadrant II or III. Thus we know that θ is in quadrant III. We use this to draw a triangle to help us find the other trig functions of θ. From the ... WebThe easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into …
