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.

welcome to this lesson. In this lesson, you'll find a cross border of I J and I minus J. Norwood. They're determined. Mattered byword properties. So, yeah, if you have a better days, E one eight to a three. Yeah, from the Director B, that is B one B two, B three. The cost for that. Their cost product is E three. Uh, the cross board that is eight to be three minus B two 83 than E three. Be one minus B three minus B three a one. Then the final part is a one B two minus B 182 Okay, so here. Well, let a B the air would be one 10 because there's no component that the cave part for A And also for this one, the B would be one negative one and zero. Okay. So that a Cosby would be. So you have eight to that is one times B three, that is zero the minus. B two, that is negative. One, an e three. That is sterile. Okay, so that is one part. The first back, the f part. Then they gave bad. We have a three that is zero then be one that is one minus B three. That is zero than a three. That is one. Okay, so that is also gone. Then we have a one. That is one be too. That is negative one, then minus. We have a one that be one that is one then eight to that is also one. Okay. And I represent the cave path. So here the air Crosby would be zero for the i component. Therefore the chief component than negative one minus one for the cave components. So here we have a Crosby, that is Yeah. Zero. I last zero j minus two key. Okay, so it Cosby would be negative. Two k. All right, so this is a time short time the end of the lesson.
