What are the formulas for law of sines and law of cosines?

In: Trigonometry [Edit categories]

Answer:

sine: sin(A) sin(B) sin(C) cosines: a²=b²+c²-2bc cos(A)
.........----- = ----- = ------
........,,,.a .......b........ c

a is side BC A is angle A sin(A) means sine of angle A

_{psst, theres a law of tangents too, but its so complicated that im not gonna post it here}
