- 21:1921:19, 14 April 2024 diff hist +1 Science:Math Exam Resources/Courses/MATH152/April 2022/Question A18 The first solution is incorrect: by reflecting the second line across the first, it actually computes Ref_30 o Ref_50, which is why the angle is clockwise (i.e. negative, which is another error in the solution). The second line should make an angle of 50º with the original x-axis.

The question statement already tells us that the composite <math>\mathit{Ref}_{50^\circ} \circ \mathit{Ref}_{30^\circ}</math> is a rotation, so we just need to compute what it does to a single vector, for example a unit vector that is fixed by <math>\mathit{Ref}_{30^\circ}</math>." current
