The 3 little division "sums" that are the Sine and its brother ratios, Cosine and Tangent, given in any basic right-angled triangle, form the basis for the entire, vast field of Trigonometry and its uses, going far beyond simple Plane Geometry into such things as Harmonic Analysis (Sine functions of amplitude with respect to time), the Laws of Electricity (starting with the phase angle between Volts and Current in a.c. circuits, etc.), and so on.

How is the law of sin used in higher levels of math like calculus or statistics?
The law of sines refers to a relationship between the sides and the angles of a triangle. Consequently, it is used in trigonometry and, to a lesser extent, in geometry. It is not really relevant in calculus or statistics.
What branch of mathematics is concerned with sines and cosines?
Trigonometry mainly but also geometry, algebra.
Can the sine law be usd in a right triangle?
Yes, the law of sines can be used in a right triangle. The law applies to any arbitrary triangle.
Which information cannot be used in conjunction with the law of sines to solve a right triangle?
Yesterday's date cannot be used.
Does the transitive property apply for the law of sines?
No, it does not.
