More complicated shapes can be represented by piecing together two or more Bézier curves. Suppose the first Bézier curve has control points P0, P1, P2, P3 and the second one has control points P3, P4, P5, P6. If we want these two pieces to join together smoothly, then the tangents at P3 should match and so the points P2, P3, and P4 all have to lie on this common tangent line. Using this principle, find control points for a pair of Bézier curves that represent the letter S.
