WebHence, sin(θ)^2 means "take the value of θ, square it, and THEN find the value of the sine function." which is very different from sin^2(θ) which means "find the value of the sine … WebSome rules to follow 19 You should know how to find an angle without using a calculator, if the angle is a variant of 0 o,30 , 45 ,60 o, or 90 . For the equation sin =𝑘your first solution, using your calculator is =sin−1𝑘. A second solution is 1800− or 𝜋− if you are working in radians. Other solutions can be found by adding or subtracting multiples of 3600or 2𝜋radians

WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebThe solutions are θ = 2π 3, 4π 3 and θ = 0 . 31. Solve 2sin2 θ −5sinθ +3 = 0 on the interval 0 ≤ θ < 2π. 2sin2 θ −5sinθ +3 = 0 (2sinθ −3)(sinθ −1) = 0 ⇒ sinθ = 3 2, sinθ = 1 The solution is θ = π 2. Note that there are no solutions to the first equation since −1 ≤ sinθ ≤ 1. steve kirsch fda hearing
