5) Consider the surfaces S1 : ryz = 10 and S2 : z =r² + y and the %3D point Po = (1,2,5).

Please help..show complete solution

a) For the parametric curve x = t^2 + 2t + 1, y = 6t + 1, find the Cartesian equation(s) forall tangent lines to this curve with slope 3. Write your line equation(s) in the point-slope form b) Plot and label the following polar point on the graph.Find the Cartesian coordinates of this point.C = (r, θ) = (4,5π/6) c) Consider the point with Cartesian coordinates (x, y) = (−1,√3)Plot this point in the (x, y)-plane.Find polar coordinates (r, θ) of this point, where r > 0 and 0 ≤ θ ≤ 2π
