Question

How to understand the trigonometry ratios ​

Answer 1

Answer:

Trigonometric Ratios

• The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). ...
• sin C = (Side opposite to ∠C)/(Hypotenuse) = AB/AC.
• cos C = (Side adjacent to ∠C)/(Hypotenuse) = BC/AC.
• tan C = (Side opposite to ∠C)/(Side adjacent to ∠C) = AB/AC = sin ∠C/cos ∠C.

Answer 2

Answer:

Trigonometric Ratios

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). ...

sin C = (Side opposite to ∠C)/(Hypotenuse) = AB/AC.

cos C = (Side adjacent to ∠C)/(Hypotenuse) = BC/AC.

tan C = (Side opposite to ∠C)/(Side adjacent to ∠C) = AB/AC = sin ∠C/cos ∠C.
