Please help with this mathlab assignment. Thanks

Part 1 Parametriza Viviani's curve is defined as the intersection of the sphere :2 + y2 + z - 4 with the cylinder (x - 1)2 + 72 - 1. Observe that 1+ cost y sin / 1 2 sin () gives a parametrization of this curve |this uses the identity sin ( ) - I cost To plot Viviani's curve use the following code syms t; x 1 cos(t); y sin(t), 2 2*sin(t/2); > fplot3(x,y,z, 10 pil ) Exercise 1.
