In mathematics, a vector (from the Latin word "vehere" meaning "to carry") is a geometric entity that has magnitude (or length) and direction. Vectors can be added to other vectors according to vector algebra. Vectors play an important role in physics, engineering, and mathematics.

In mathematics, a vector (from the Latin word "vehere" which means "to carry") is a geometric object that has a magnitude (or length) and direction. A vector can be thought of as an arrow in Euclidean space, drawn from the origin of the space to a point, and denoted by a letter. The magnitude of the vector is the distance from the origin to the point, and the direction is the angle between the direction of the vector and the axis, measured counterclockwise.

Okay, so we have an equation. X square plus was weeks poor. So Okay, this is the circle in art too. But what does it represent? Our three we're first in the jaw is graphene are too explain. See, the a reason O So the readers of the circles too, So happy we are to use this. So now with hidden in whoa recorded See what we can see That there's no Z in the equation. So the circle as a swear Rico's a square passwords for export It just a projection of the whole graft onto the ax or what? Plea. So now he is free the means we can too see freely from the whole room number. So finally, the regions or the graph of this equation after it's gonna be like a silent here. So it's like a Southerner and yes, we cutting If we cut it comes that under. In that parallel to ATS wise could be like a circle which is parallel. Two is production onto oh Wayne train. So, Ravi, the gravis will in this. But the length of it is infinite because you go through the whole rule number off the the White Z coordinates go through the whole room number. So this Salinger with even then this
