WebThe sine, cosine, and tangent ratios in a right triangle can be remembered by representing them as strings of letters, for instance SOH-CAH-TOA in English: . Sine = Opposite ÷ Hypotenuse Cosine = Adjacent ÷ Hypotenuse Tangent = Opposite ÷ Adjacent. One way to remember the letters is to sound them out phonetically (i.e. / ˌ s oʊ k ə ˈ t oʊ ə / SOH-kə … WebDo you mean the "Reciprocal functions" like secant and cosecant. The inverse trigonometric functions (the cyclometric functions) are represented by arcosine, arcsine etc. Reciprocal functions were used in tables before computer power went up and there are some instances where calculating an inverse of a function is easier than the function.
