This example is a quadratic equation, so let's treat it like one. get Go. Solving for sin(x), we have the following: For the second solution, we have these steps: Get access risk-free for 30 days, For example, domains might be limited to 0° to 180°, 0° to 360°, -180° to 180°, etc. As a side note, remember that some trig problems work in radians instead of degrees.

Radians use the π properties of a circle, and instead of expressing angles as part of a 360° circle, they express angles as a part of a 2π circle.

Mathway currently does not support this subject. A domain limitation establishes upper and lower limits for possible input angles, otherwise you have to allow for an infinite number of solutions in positive and negative rotations.

Trigonometric equations can be solved in a similar way to normal functions.
