how do I solve the following question about electric fields and dipoles?

4. The electric field at r = (r, 0) due to an ideal dipole p placed at the origin can be expressed as Edipole (r, 0) = - P ATEor3 (2 cos Of + sin 0 0), where O is the angle between p and r. a) Find the magnitude and the direction of the electric field at point P, which is at a distance y along the direction of the dipole. Express your answer without using r or 0. b) Find the magnitude and the direction of the electric field at point Q, which is at a distance x perpendicular to the direction of the dipole. Express your answer without using r or 0. . P p
