WebThe period is 360° so to find the next solutions subtract 360°. The solutions to the equation \ (\sin {x} = 0.5\) are: \ (x\) = -330°, -210°, 30° and 150°. Question Solve the equation \ (\cos... Web28 Sep 2024 · Simplify sin 150° into sin (90° + 60°). Further, we can say sin ( (1 × 90°) + 60°) Now as we have an odd coefficient of 90°, sin changes to cos. Also, it is covering 90° in the first quadrant and again added 60° leads to the second quadrant. In the second quadrant, we know sine is positive. The final result will be cos 60°.
