I need help with these Any help will be appreciated

1. Find a parametrization for each of the following surfaces. Specify the domain of pa.- rameters. (a) the plane through {1, 2, 1) perpendicular to the vector (1, 2, 3). {b} the plane through {1, 2, 1) parallel to the vectors ([1, 1, 3} and (2, O, 7). {c} the surface S : 2:2 +33; +22:2 +4: 0. (d) the part of the sphere 1:2 + y: + 22 = 16, at 32 2 (use y, 3 as parameters}. {e} the part of the sphere 1:2 + y1| + 22 = 161 z 3} 2 (use spherical coordinates}
