Vectors and matrices by Marco Taboga, PhD This lecture provides an informal introduction to matrices and vectors.

Linear Algebra is strikingly similar to the algebra you learned in high school, except that in the place of ordinary single numbers, it deals with vectors.

Students then use matrices to study and solve higher order systems of equations. Vectors are introduced, and students study the arithmetic of vectors and vector magnitude.

Consider two vectors A and B in three dimensions: The magnitude of kA Bk is equal to the area of the parallelogram formed using A and B as the sides. The angle between A and B is: kA Bk = …

Distance, speed, time, temperature, mass, length, area, volume, density, charge, pressure, energy, work and power are all scalars. A vector has magnitude and direction: Displacement, …

We are doing algebra with numbers while we are doing geometry with vectors. It was the great contribution of Descartes to see how to study algebra and geometry at the same time.

An induced matrix norm is a particular type of a general matrix norm. Induced matrix norms tell us the maximum amplification of the norm of any vector when multiplied by the matrix.

Mar 10, 2025 · Matrices are used to represent data in a structured way, while vectors are used to represent quantities that have both magnitude and direction. These concepts are essential for …

Feb 23, 2025 · I'm telling you all of this for two reasons: first, some physics professors said they wished freshmen would learn about vectors and matrices sooner, and second, because …
