Trigonometric Ratios
A right-angled triangle can be
solved by using any of six trigonometric ratios. These are Sine
(Sin),
Cosine (Cos), Tangent (Tan), Cosecant (Cosec), Secant
(Sec), and Cotangent (Cot).

Sine and
Cosine Formulas
In any triangle,
say ABC, containing angles A, B and C in degrees with sides a, b and c, |
 |
The Sine Formula states:
a = b
=
c
Sine
A Sine
B Sine C |
The Cosine Formulas
state:
a²
= b² + c² - 2bcCos A
b²
= c² + a² - 2caCos B
c²
= a² + b² - 2abCos C |
