Question

let(r,Ф)represent the polar coordinates describe the position of a particle if r^ is a unit vector in the direction of the positive vector r and Ф is a unit vector perpendicular to r and in the direction of increasing Ф show that
1) r^=cosФi+sinπФj, Ф^=-sinФi+cosФj
2)i=cosФr+sinФФ^, j=sinФr^+cosФФ^
