The Sine Rule
The sine rule is a vital formula for any trigonometry enthusiast.
(a/sin A) = (b/sin B) = (c/sin C)
It relates the lengths of the sides of a triangle to the sines of its angles.
The Cosine Rule
The cosine rule is another essential tool in the trigonometry toolkit.
c² = a² + b² - 2ab * cos(C)
This rule helps find the length of a side in any triangle or the angles.
