This math video tutorial gives a step by step explanation to a math problem on "Finding Trigonometric Values Using Sohcahtoa".

Finding trigonometric values using sohcahtoa video involves functions, identities, sohcahtoa, trigonometric functions, trigonometric identities. The video tutorial is recommended for 9th Grade, 10th Grade, and/or 11th Grade Math students studying Algebra, Trigonometry, Pre-Calculus, and/or Advanced Algebra.

Students often use mnemonics to remember facts and relationships in trigonometry. For example, the sine, cosine, and tangent ratios in a right triangle can be remembered by representing them as strings of letters, as in SOH-CAH-TOA.

Sine = Opposite ÷ Hypotenuse

Cosine = Adjacent ÷ Hypotenuse

Tangent = Opposite ÷ Adjacent

Alternatively, one can devise sentences which consist of words beginning with the letters to be remembered. For example, to recall that Tan = Opposite/Adjacent, the letters T-O-A must be remembered. Any memorable phrase constructed of words beginning with the letters T-O-A will serve.

In mathematics, the trigonometric functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle.
