Question

Derive the law of sine and cosine for two vectors.

Answer 1

Answer:

The direction angle θ of the resultant in the Polar (positive) specification is then θ = α + 60°. The Law of Cosines is used to calculate the magnitude (r) and the Law of Sines is used to calculate the angle (α). ... Using the Law of Cosine and Sines, calculate the resultant (sum) of the following two vectors.

Answer 2
