Please help me with this problem can you do it step by step

Find an equation for the plane tangent to the cone r(r,6)= (r cos 6) i+(r sin 0)j+rk, r20, 0565221, 1: at the point P0 (0,2,2) corresponding to (r,6) = [2,5] . Then nd a Cartesian equation for the surface and sketch the surface and tangent plane together. 0 Click here for more information about the plane tangent to a parametrized surface. The tangent plane at a point P0(x,y,z) on a parametrized surface r(r,9) = (r cos 6)i + (r sin 6)] + r k is the plane through P0 normal to the vector rr x re, the cross product of the tangent vectors at P0 . What is the equation of the tangent plane? D=0 (Type an expression using x, y, and 2 as the variables. Type an exact answer, using radicals as needed.)
