Sum of the two vectors - the result
Sum of vectors (size, magnitude) F = F1 + F2 = 13.228756555323
Directional angle of the resulting vector φ = 40°53'36″ = 40.893394649131° = 0.2271855 rad
How to add two vectors
If we place the vectors at one starting point, the vectors form two sides of the parallelogram. By completing the remaining two parallel sides, we create a parallelogram. The resulting vector of the sum is the oriented diagonal of this parallelogram starting at the location point of the vectors.Analytically - by calculation, we calculate the sum of vectors most simply by dividing the vectors into x, y, or z components. We then add the individual vectors by components. We then calculate the size of the resulting vector from the Pythagorean theorem from its component form. We determine the direction vector trigonomically - by the arctangent of the y:x ratio.
