In general we note the transformation of the vector x as T(x). We can think of this as the transformation operator “acting on” the vector x to yield a new vector T(x). In general, the number of elements in x and T(x) can be different (i.e. x could be a vector in R3 while T(x) is a vector in R2).

Linear transformations are a special type of transformation, and as such, satisfy certain properties. Linear transformations always have a matrix representation.

In this problem we consider a linear transformation that takes vectors from R3 and returns a vector in R3. The matrix representation of this linear transformation is provided and we compute T(x) for several different values of x.

http://www.freemathvideos.com In this video series I will show you how to write the equation and graph hyperbolas. Hyperbolas on a graph represent two parabolas facing away from each other but the definition of a hyperbola is the difference between the distance of a set of points and the foci are equal for all points. Just…
