Trigonometry is a branch of mathematics that studies relationships involving lengths and .... These ratios are given by the following trigonometric functions of the known angle A, where a, b and c refer to the lengths of the sides in the ...
The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
Intro to the trigonometric ratios. AboutTranscript. Sal introduces sine, cosine, and tangent, and gives an example of finding them for a given right triangle.
For any right triangle, there are six trig ratios: Sine (sin), cosine (cos), tangent (tan ), cosecant (csc), secant (sec), and cotangent (cot). Here are the formulas for ...
