At what point do the curves r1 = t, 1 - t, 3 + t^2 and r2 = 3 - s, s - 2, s^2 intersect? And what is the angle of intersection?

At what point do the curves r1 = < t, 1 - t, 3 + t^2 > and r2 = < 3 - s, s - 2, s^2 > intersect? And what is the angle of intersection?

Solution:Given equations: and When x, y, and z coordinates are all equal at the same timex-coordinates:y-coordinates:z-coordinates:Equations we get from x- and y-coordinates both give us...
