1 Given two points =(1,1,1) and P = (-10,3,7), Do the followings: (1) Find the line equation P(t) which starts at P(0)-P and ends at P(1)-P. (2) Calculate the point which divides the line in a ratio of 0.3:0.7. 2 Find the equations for the tangent line to the curve F(t)=(3 cost,3 sint,10r) at 1= x/2.
