Mathematics for IGCSE & O level - Vectors (Section 5 - No. 1)
Given vector v = [x, y], which statement is correct?
The magnitude of v is √(x^2 + y^2).
If x = 0 and y = 0, then the magnitude is 1
The direction can be defined by the angle from the x-axis.
The magnitude is always positive.
Selitys
The magnitude is the square root. The direction is defined by the angle. Magnitude is always positive.
