# Mathematics Articles: 10-Minute Trig

Here’s a quick review of the basic facts of right-angle trigonometry complete with examples and definitions. Use the mnemonic, SOHCAHTOA, to remember how to compute the sine, cosine, and tangent of an angle. The equations to find the trigonometric ratios of acute angles are presented. Review the trig functions of any angle, including special angles. This site references a much larger site, Trig without Tears, for more review and explanation should you need it.
