!!! Overview [{$pagename}] implies there must be no curves (only lines) and the origin must remain fixed. Think of linear transformations as keeping gridlines parallel and evenly spaced. [{$pagename}] is a [Function] (or [Algorithm]). So a linear Function is a Function that takes a [vector] input and outputs a [vector]. [{$pagename}] implies there must be no curves (only lines) and the origin must remain fixed. Think of linear transformations as keeping gridlines parallel and evenly spaced. [Basis vectors] define the coordinate system or origin. Commonly * iHat (x-axis) * jHat (y-axis) * kHat (z-axis) are used. [{$pagename}] requires that you perform [matrix multiplication] of the [vector] by the changes to the [Basis vectors] (iHat, jHat) Any [{$pagename}] can be described as iHat and jHat this is because any other vector could be described as a linear combination of those [basis vectors] a [vector] with coordinates x, y is x times iHat plus y times jHat !!
