I don't know exactly what kind of report you have to do but I'll provide some websites with some vector definitions, explanations and examples.

Use the regulation of cosines once you have the vectors in polar form meaning value and attitude. Your vectors are in oblong that's greater powerful because of the fact then all you do is upload horizontals and verticals (6+4)i + ( 8-3)j = 10i + 5j => value = sqrt[a hundred+25] = eleven.2 Convert yours to polar: P = sqrt[36+sixty 4] at arctan(8/6) = 10 at fifty 3.13 deg Q = sqrt(sixteen+9) at arctan(-3/4) = 5 at -36.87 deg (or =323.13deg)
