Sines, cosines, and tangents, oh my! But there’s more: Use Desmos to easily graph inverse trig relations and functions, or to build interactive unit circles and sine wave tracers. Switching between radians and degrees is a breeze (click the wrench icon), and you can even display pi labels on the axes.
If we know one of the sides of a right triangle and any one of the other four parts, we can use trigonometry to find all the other unknown parts. If we know one of the trigonometric ratios of an acute angle, we can find the angle using the inverse trig key on a calculator.
