Question

In application level, law of sine is used to find direction or angle and law of cosine is used to find the magnitude of resultant vector. is this true?? if not, Why ????​

Answer 1

Explanation:

How do you find the direction of the resultant vector?

The direction of the resultant can be determined by finding the angle that the resultant makes with either the north-south or the east-west vector. The diagram at the right shows the angle theta (Θ) marked inside the vector addition triangle. This angle theta is the angle that the resultant makes with west.

Answer 2

The direction of the resultant can be determined by finding the angle that the resultant makes with either the north-south or the east-west vector. The diagram at the right shows the angle theta (Θ) marked inside the vector addition triangle. This angle theta is the angle that the resultant makes with west..
