How does this law of cosines calculator work? Together with the law of sines, the law of cosines can help in solving from simple to complex trigonometric problems by using the formulas provided below. how to write precision 5g The cosine rule tells us that when we have a right triangle, c o s i n e = a h cosine = \frac{a}{h} c o s i n e = h a . The " a " in this case stands for adjacent. The " h " stands for the hypotenuse, which can be found through the pythagorean theorem .
