How do you find the trigonometric ratio
WebFor 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 these six trig ratios: Given a triangle, you should be able to … WebThere are six ways to form ratios of the three sides of this triangle. In the following tables, I'll shorten the names from "hypotenuse", "adjacent", and "opposite" to "hyp", "adj", and "opp", respectively. The tables below show the six ratios in the center columns. Ratios in same-color rows of each table are reciprocals of each other.
