Law of Sines
The Law of Sines is defined as:
\[ \frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)} = 2R \]
Where:
- a, b, c are the lengths of the sides of the triangle
- A, B, C are the angles opposite to sides a, b, c respectively
- R is the radius of the circumscribed circle
Properties:
- Works for any triangle
- Relates sides and angles of a triangle
- Can be used to find missing sides or angles
- Useful for solving ambiguous cases
Applications:
- Navigation and surveying
- Physics (wave motion)
- Engineering (structural analysis)
- Astronomy
- Computer graphics
Common Cases:
- Acute triangles
- Right triangles
- Obtuse triangles
- Ambiguous case (SSA)
