1. The problem statement, all variables and given/known data Suppose T is a rotation by 30 degrees about the point 2, and S is a rotation by 45 degrees about the point 4. What is T composed with S? Can you describe this transformation geometrically? 2. Relevant equations none 3. The attempt at a solution I know T composed with S means S is the first transformation we want to do, and T is second. But I'm not sure how we can rotate about the point 4, and then rotate about the point 2.
