Extracted text: The parametric equations for the motion of a charged particle released from rest in electric and magnetic fields at right angles to each other take (1 – cos 0). Show that the tangent to the curve has slope cot () Use this result at a few calculated values of a and (0 – sin 0),y = y to sketch the form of the particle's trajectory. the forms x = a
