The vector parameter equation is an equation in high school mathematics, and the expression is: OP=( 1-t)OA+tOB.

2, vector addition and subtraction:

A(X 1, Y 1) B(X2, Y2), then A+B=(X 1+X2, Y 1+Y2), A-B=(X 1-X2).

3. Multiply the number by the vector:

Law of constraint: λ (μ a) = (λ μ) a;

The first distribution law: (λ+μ) a = λ a+μ a;

Second distribution law: λ (a+b) = λ a+λ b.

Development history

Vector, originally applied to physics. Many physical quantities such as force, velocity, displacement, electric field intensity and magnetic induction intensity are vectors. Around 350 BC, Aristotle, a famous ancient Greek scholar, knew that force can be expressed as a vector, and the resultant force of two forces can be obtained through the famous parallelogram rule.

The word "vector" comes from directed line segments in mechanics and analytic geometry. Newton, a great British scientist, was the first to use directed line segments to represent vectors.
