Parameterise the following paths, in the dirction stated, and hence find a tagent vector(in the same dirction) to each point on the paths.

(a)The upper part of the circled centred at (0,0) containing the points (-2,0) and (2,0) going anticlockwise.

(b) the circle centred at (1,2,5) of radius three in the plane z=5 going clockwise (looking down the z axis)
