Final answer:
To sketch the graph of each vector valued function, determine the x and y (or z) components of the vectors.
Step-by-step explanation:
To sketch the graph of each vector-valued function, we need to determine the x and y components of the vectors. For function a: (t) = (Acos(t), Bsin(t)), the x and y components are given by Ax = Acos(t) and Ay = Bsin(t). For function b: (t) = (3+1,1+21,1-t), the x, y, and z components are given by Ax = 3+1, Ay = 1+21, and Az = 1-t.
