Problem 8

Let a rectangular xy-coordinate system be given and a second rectangular coordinate system x'y' be obtained from it through a rotation through an angle () about the origin. An arbitrary point Pin the plane has coordinates [] relative to the xy-coordinate system and coordinates [:] relative to the x'y'-coordinate system. Use trigonometry to prove that the coordinate transformation is x' = x cos() + y sin() y' = x sin() + y cos()
