A point with coordinates x and y is rotated in an anticlockwise direction through an angle z, so that its distance from the origin of the coordinate system remains constant. Show that the new x and y coordinates become

xcosz - ysinz and xcosz + ysinz respectively.

2. Relevant equations

3. The attempt at a solution

Well im looking for some advice on how to start this! The wording is confusing to me! To my mind surely if you rotate a point it will be exactly the same??? Any help would be supremely appretiated.
