what are the three primary trig ratios The Six trigonometric ratios are sine cosine tangent secant cosecant and cotangent The trigonometry ratios are the ratios of sides of a right triangle Sin cos and tan are primary ratios
In this module we will review the primary trigonometric ratios and how they can be used to find missing side lengths or angles in a right triangle Basic trigonometry Khan Academy Finding a Side Transcript Sin cos and tan are trigonometric ratios that relate the angles and sides of right triangles Sin is the ratio of the opposite side to the hypotenuse cos is the ratio of the adjacent side to the hypotenuse and tan is the ratio of the opposite side to the adjacent side They are often written as sin x cos x and tan x

There are six common trigonometric ratios that relate the sides of a right triangle to the angles within the triangle The three standard ratios are the sine cosine and tangent These are often abbreviated sin cos and tan Trigonometric ratios are the ratios of the length of sides of a triangle These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle The basic trigonometric ratios are sin cos and tan namely sine cosine and tangent ratios
Three common trigonometric ratios are the sine sin cosine cos and tangent tan There are three more trigonometric ratios cosecant cosec secant sec and cotangent cot that is the inverse of sine cosine and tangent High school geometry Right triangles trigonometry Introduction to the trigonometric ratios Trigonometric ratios in right triangles Google Classroom About Transcript Sal shows a few examples where he starts with the two legs of a right triangle and he finds the trig ratios of one of the acute angles Created by Sal Khan
