Prove that the equation of the line through a and normal to the plane x n=d, |n|0, is xkn+a, - < < . Prove that the equation of the line through a and orthogonal to c and d, cxd0, is x=k(ex d) + a. Find the equation of the cone with vertex at A(0, 1, 1), with axis parallel to the x1 axis, and half angle = 60.
