1.Consider the process A[1,1] and B [-1,4]; let Vector U=AB
1a.Write u using components. Write u using the standard basis.
1b.Draw u as a position vector. Find u.
1c.If C [1,1] and D [5,y], then find the value of y so that AB is parallel to CD.
2. Find the length of the curve 2t2 3t2 , 0<t<[3/4]
3. Find the equation of the sphere with center [2,3,4] and is tangent to thee xyplane. At what points does the sphere intersect the z axis?
2.distance formula
3.
My Answers
1a. -1-1=-2 4-1=3 u=<-2,3> u=<1,1> <-1,4>
1b. u=-22+32[1/2] =131/2
1c. [5-1/2],[y-1/2] [2,y-1/2]
