So what is a vector. Know more about these in vector algebra class 12 formulas pdf with notes list. The length of the line shows its magnitude and the arrowhead points in the direction. It is non negative scalar.
Scalar and vector elds. Two arrows represent the same vector if they have the same length and are parallel see gure 131. This course will remind you about that good stu but goes on to introduce you to the subject of vector calculus which like it says on the can combines vector algebra with calculus.

The pdf version will always be freely available to the public at no cost. The length or magnitude of a vector v is defined to be the common length of the representatives of v. Vectors algebra and geometry 21 vectors a directed line segment in space is a line segment together with a direction. We use vectors to represent entities which are described by magnitude and direction.
Vector algebra a vector has direction and magnitude both but scalar has only magnitude. Vector algebra and calculus 1. Vector algebra 425 now observe that if we restrict the line l to the line segment ab then a magnitude is prescribed on the line l with one of the two directions so that we obtain a directed line segment fig 101iii.
