Geometry - Transformation using matrices - Math
Learn how to rotate a vector by 90 degrees using matrix form in this step-by-step tutorial. We start by defining vector A, which is drawn graphically, and then multiply it by the rotation matrix R to obtain vector B. We simplify the calculation by multiplying each row by the corresponding column and then adding the results. Finally, we draw vector B graphically, connecting its points to form the vector. Follow along with the video to learn more about rotating vectors in matrix form!
