WebSolve the problem exactly: 2sin2θ − 1 = 0, 0 ≤ θ < 2π. Solution As this problem is not easily factored, we will solve using the square root property. First, we use algebra to isolate sinθ. Then we will find the angles. 2sin2θ − 1 = 0 2sin2θ = 1 sin2θ = 1 2 √sin2θ = ± √1 2 sinθ = ± 1 √2 = ± √2 2 θ = π 4, 3π 4, 5π 4, 7π 4 Analysis WebSine, Cosine and Tangent. The three main functions in trigonometry are Sine, Cosine and Tangent. They are easy to calculate: Divide the length of one side of a ... Example: Solve sin θ = 0.5. We get the first solution from the calculator = sin-1 (0.5) = 30º (it is in Quadrant I) portable axshield vpn
