9. A line L1 is drawn between two points P1 (3,5,9)and P2(6,7,3) 2 2 L5
and L2 is drawn between P3(6,5,3) and P4(3,8,9). Find the
parametric equation and tangent vector of the line. Also
determine are the two lines intersecting each other If yes find
the point of intersection.
Write the parametric equation of a circle having center at (3, 3,
0) and a radius of 3 units. Calculate the coordinates of points on
a circle if it is divided in eight parts.
10. Plot the hermite cubic curve having end points A (1, 3) and B 2 2 L5
(7, 2). The tangent vector for end A is defined by a line joining
A and another point C (10, 8), whereas the tangent vector for
end B is defined by a line joining B and another point D (6, 0).
Also plot the curve, if the point D is changed to (9, 6), with the
other things remains same.
