Use SOH-CAH-TOA to define sin, cos and tan.Identify the opposite, adjacent and hypotenuse.Compute a ratio from side lengths.Recall what each mnemonic stands for.📚 Quick Recap
Trigonometric ratios connect the angles of a right triangle to the ratios of its side lengths — the foundation for everything else in trigonometry.
