Vectors
Break each vector into x and y components.
Add the two x & y components to get the x/y component
of the resultant, R
Now convert resultant into magnitude and angle
Alternate Method for magnitude
Cosine rule
Cross Product
The cross product 𝐚×𝐛 is defined as a vector 𝐜 that is
perpendicular to both 𝐚 and 𝐛, with a direction given by the
righthand rule and a magnitude equal to the area of the
parallelogram that the vectors span.
If 𝐚 = a₁𝐢 + a₂𝐣 + a₃𝐤
