WebTrigonometry. Find the Other Trig Values in Quadrant I sin (theta)=8/17. sin(θ) = 8 17 sin ( θ) = 8 17. Use the definition of sine to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values. sin(θ) = opposite hypotenuse sin ( θ) = opposite hypotenuse. Find the adjacent side of the unit ... WebMar 29, 2016 · I unveil the mysteries and secrets of trigonometry & you'll love it. The given cosecant value means, equivalently, that sin θ = -2/3. Then cos (2θ) = 1-2sin 2 (θ) =. 1- (-2/3) 2 = 1 - 4/9 = 5/9. That answer is wrong. It should be. 1- (2) (-2/3) 2 = 1/9. Hatha has caught a mistake that I made in the last line of solution offered in March ...
