In this lesson we deal with a velocity problem using vectors.
In this lesson we discuss how to find a vector joining 2 vectors from the origin.
In this lesson we talk about a different kind of notation for vectors using angle brackets (not curly brackets because that would be specifying a point not a vector). We then talk about a quick way to find a vector joining any 2 points on the Cartesian plane.
In this lesson we talk about how to find the unit vector in the same direction as any vector expressed in terms of i and j.
In this video we solve a word problem involving vectors. Have a go at it to see whether you know everything we have done so far!
In this lesson we talk about how to find the x and y components of a vector given its magnitude and direction, by drawing a right angle triangle with the x axis and using trigonometry.
In this lesson we talk about – Given a position vector, how to find its magnitude. – Given a position vector, how to find its direction (as a compass bearing).
In this tutorial we extend the position vectors concept to draw vectors in 3D, using unit vectors i, j, and k.
In this lesson we define unit vectors i and j as vectors moving along the x or y axis with a magnitude of 1. Then we define position vectors using unit vectors.
Today we discuss what scalar multiplication means for vectors, and we do some addition / subtraction examples combined with scalar multiplication.
