1 # Rotation 2 3 Khan U2 4 5 **Definition:** A rotation is a linear transformation (assuming the rotation axis passes through the zero vector) that rotates about some axis theta degrees **counter clockwise**. 6 7 ## Create Matrix 8 9 To create a matrix to represent a rotation do the following: 10 11 1. Start with identity matrix 12 2. Calculate each individual basis vector under the rotation we want (use trig) 13 3. Aggregate the results into a final matrix where each column is the result of the basis vector transformation 14 15 This is the same way we normally create the [StandardMatrix](StandardMatrix.md) of a L.T. for other transformations.
