Pi/2 can be written as 90 degrees Sin(90theta) lies in the 2nd quadrant where the Sines before conversion remain positive and since the value is changing through a multiple of 90 degrees, the trigonometric function will change Hence, Sin(90theZ π 2 0 cos2θ dθ 23 Z π 2 0 cos2θ dθ correct 33 Z π 2 0 cosθ dθ 43 Z π 0 cos2θ dθ 53 Z π 0 cosθ dθ Explanation r = 2cosθ and r = cosθ intersect atθ = π 2 Because of symmetry with respect to the xaxis, A 2 = 1 2 Z π 2 0 4cos2θ dθ − 1 2 Z π 2 0 cos2θ dθ A = 3 Z π 2 0 cos2θ dθ CalC11d01b 005 100points The1) Amy and Dex 2) Beth and Carl 3) Carl and Amy 4) Dex and Beth 2 A circle with a diameter of 10 cm and a central angle of 30° is drawn below What is the area, to the nearest tenth of a square
