Web1.5 = cot θ = cos θ sin θ hence 1.5 sin θ = cos θ. Squaring both sides we have 2.25 sin 2 θ = cos 2 θ and since cos 2 θ = 1 − sin 2 θ we have 2.25 sin 2 θ = 1 − sin 2 θ 2.25 sin 2 θ + sin 2 θ = 1 3.25 sin 2 θ = 1. From this, you can figure out the value of sin 2 θ. Taking square roots will tell you something about the absolute value of sin θ. WebExplanation: For cos 60 degrees, the angle 60° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 60° value = 1/2 or 0.5. Since the cosine function is a periodic function, we can represent cos 60° as, cos 60 degrees = cos (60° + n × 360°), n ∈ Z. ⇒ cos 60° = cos 420° = cos ...
