Linear relationships can be expressed either in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable ...

Almost anything will work, but why not take the simple example ... of functions, but not nearly interesting enough for calculus purposes. While I do spend lots of time pushing the idea of linear ...

Elementary set theory and solution sets of systems of linear equations. An introduction to proofs and the ... Inner products. Matrix algebra. Applications of the above will also be discussed.

This means equations are not always true. In the example above, \(3x + 5 = 11\), the only correct solution for \(x\) is 2. An identity is an equation which is always true, no matter what values ...
