2 cards from this section. Quick, good the night before a test.
What is the matrix representation of a point in 2D?
Think of how we represent coordinates in a plane.
Name a type of transformation that alters the size of an object.
Consider transformations related to measurements.
What is the matrix representation of a point in 3D?
Remember how we extend 2D to 3D.
True or False: The order of matrix multiplication for transformations does not matter.
Consider how different orders affect the result.
Consider a point P(2, 3) being translated by T(4, 5) and then rotated by 90 degrees. What is the final position of P?
Remember the order of operations when transforming points.
If a scaling transformation enlarges an object by a factor of 3 and a translation shifts it right by 5, what would be the transformation matrix for this combined process?
Consider how to multiply matrices to combine transformations.
