Law of cosines with a right angle?
The law of cosines with a right angle is just the pythagorean theorem. The cosine of 90 degrees is 0. That is why the hypotenuse squared is equal to the sum of both of the legs squared
What are the answers to law of cosines in A plus?
The law of cosines can be written in one form as: c2 = a2 + b2 - 2abCos C. Without 3 of the 4 variables being given, there is no way to answer this question.
Can the law of cosines be applied to right and non-right triangles?
Yes
What branch of mathematics is concerned with sines and cosines?
Trigonometry mainly but also geometry, algebra.
How are all three versions of the law of cosines correct?
It follows from the cyclical symmetry of the cosine rule.
How are sines and cosines used in meteorology?
In trigonometry sines and cosines are used to solve a mathematical problem. And sines and cosines are also used in meteorology in estimating the height of the clouds.
Are direct cosines of a vector unique?
No, the direct cosines of a vector are unique only up to a sign change. This means that if a set of direct cosines uniquely defines a vector, a set of direct cosines with opposite signs for all components would define the same vector.
Who discovered the law of cosines?
A caveman from 10,000 BCal-Kashi was the 1st to provide an explicit statement of the law of cosines in a form suitable for triangulation
How do you calculate the angles of a triangle knowing the sides?

When you have a right angle what does the law of cosines reduce to?
cosine = adjacent/hypotenuse
Can the law of cosines be applied to right and non-right triangles?
Yes
What does the law of cosines reduce to when dealing with a right triangle?
D. The Pythagorean Theorem
Can The law of cosines can only be applied to acute triangles?
No, it applies to all triangles.
Is it true that the law of cosines reduces the Pythagorean theorem with right triangles?
Yes
Can law of cosines can only be applied to acute triangles?
No, it applies to all triangles.
