WebFeb 14, 2024 · We want to see if in the interval [0, 2π) can the sine and cosine values of radian measures ever be equal. So we basically want to solve: sin (θ) = cos (θ) or: sin (θ)/cos (θ) = tan (θ) = 1 Now we can apply the inverse tangent function, Atan (x) to both sides, so we get: Atan (tan (θ)) = Atan (1) θ = 0.785 rad WebThe value of sin 2 degrees can be calculated by constructing an angle of 2° with the x-axis, and then finding the coordinates of the corresponding point (0.9994, 0.0349) on the unit …

But there is an important "double-angle" identity (1) sin ( 2 θ) = 2 sin ( θ) cos ( θ) that you can use in your problem. If you know that sin ( θ) = x 3, all you need to do to find sin ( 2 θ) is to find cos ( θ) and then use the Identity (1). Share Cite Follow answered Oct 1, 2014 at 3:47 André Nicolas lambagear bird
