SOHCAHTOA: A Mnemonic for Memory A straightforward method to remember these definitions is the mnemonic device SOHCAHTOA, which stands for Sine equals Opposite over Hypotenuse, Cosine equals Adjacent over Hypotenuse, and Tangent equals Opposite over Adjacent. By visualizing the triangle and labeling the sides correctly, you can reliably apply these rules to find unknown values.
Essential Trigonometry Rules for Sin, Cos, and Tan
This identity, along with others, allows for the simplification of complex expressions and the solution of trigonometric equations. On a circle with a radius of one, the cosine of the angle corresponds to the x-coordinate of the point where the terminal side of the angle intersects the circle, while the sine corresponds to the y-coordinate.
The tangent of θ is the ratio of the length of the opposite side to the length of the adjacent side. The sine, cosine, and tangent functions describe the ratios of the sides of a right triangle relative to its angles, providing a powerful toolkit for modeling periodic phenomena and solving spatial problems.

The tangent function is then the ratio of sine to cosine, representing the slope of the line segment connecting the origin to that point. This repetition occurs every 360 degrees or 2π radians for sine and cosine, and every 180 degrees or π radians for tangent, a property known as periodicity.
