Direction angle of a vector
It should be clear by now that a quantity will not be considered a vector quantity if the magnitude or the direction is missing. In this section, we will shift our focus to learn how to indicate the direction of a vector.
Basic Concepts: Use sine ratio to calculate angles and sides (Sin = ho ), Use cosine ratio to calculate angles and sides (Cos = ha ), Use tangent ratio to calculate angles and sides (Tan = ao )
Related Concepts: Angle and absolute value of complex numbers
