Determine whether the lines 11 and 12 are parallel, coincident, skew, or intersecting. If they intersect, find the point of intersection: 1 : x1(t) = 3 + 2t, y?(t)=-1 +4t, (t) = 2 – t. 12 : x2(u) = 3 + 2u, v2(u) = 2 + u, z2(u) = -2 + 2u a) O Coincident b) Skew c) Intersect at (1, -5,3) d) Intersect at (-1,-1,-1) e) O Parallel but not coincident f) None of the above. Find the unit tangent vector and the principal normal vector, and an equation in x, y, - for the osculating plane at the point on the curve corresponding to the indicated value of t. r(t) = (2)i + (2t)j+tk t=1 a) º (T - ? v7j+V7 k, N--vz + 17 k, plane: (x ? 2) =0) b) (1-5v7j+?v7k, N--5v7j+v7k, plane (12-1)--) c) • (I -- v2j- ? v2 k, N=v2j+? v2 k, plane (x - 2) =0) a) • (T-ývajt ? V7 k, N- ? V7;- ? v2k, plane: (x + 2) –0) 6) (1 - 4v7j+ ? v7k, N--ý v7i+ ? v7 k, plane (2x+4) =o) f) None of the above.
