Mathematics for IGCSE & O level - Vectors (Section 4 - No. 34)
If a and b are position vectors and a + b = c, which statement best describes the relationship?
a and b are perpendicular.
c represents the sum of the vectors a and b.
a and b are parallel.
c represents the difference between the vectors a and b.
Vysvětlení
The sum of two position vectors results in a new position vector that can be found using the triangle or parallelogram rule.
