R 1 = R Proof: As discussed at the bottom of page 259, the rotation R0 is a rotation by an angle of 0, which means R0 doesn't rotate anything at all. It's the identity function on the plane.

Rotating Quadratic Equations To eliminate the -term in the general quadratic equation xy Ax2 + Bxy + Cy2 + Dx + Ey + F = 0 where = 0 B 6 ; ; rotate the coordinate axes through an angle that …

Examples Question 2: Rotate each of the shapes below as instructed, using the origin, (0,0), as the centre of rotation. Question 3: Rotate each of the shapes below as instructed. Question 4: …

An Example Given the point matrix (four points) on the right; and a line, NM, with point N at (6, -2, 0) and point M at (12, 8, 0). Rotate the these four points 60 degrees around line NM (alone the …

When we rotate we will want to have a square viewing centered at the origin, and the output suggests the viewing window [-6,6]x[-6,6] will be appropriate to show all of the rotated graphs.

Check using the Cube • Use N to rotate the cube with corners at rotate the cube into itself. Take the vertices does in fact transform to another • Use T to rotate the cube. For what 4 angles • …
