Chapter 13, Section 13.6, Question 033 Find Vz. 7 = sin (4y - 6xy) Give your answer in unit vector notation; that is, in terms of i and j. VZ= ? EditChapter 13, Section 13.7, Question 017 (a) Find all points of intersection of the line x=-1+t, y =4+t, z = 6f + 19 and the surface z=x+ (b) At each point of intersection, find the cosine of the acute angle between the given line and the line normal to the surface. Enter your answers in order of ascending x-coordinate value. (a) (b) (X1 . )1 . Z ) = (,0,0 Edit cos 01 = Edit (x2+ 12, 22) = Edit cos 62 = ? EditYour answer is partially correct. Try again. Use the fact that N () can be expressed directly in terms of r () as NO = Ilu () II where to find N (t) . r () = sint . i+ cost . j +t . k Answer: N(1) = N . i+Nj . j + Me . k where NE X V2 Edit N; = * 2 Edit N =Chapter 12, Section 12.1, Question 003 Find the domain of r() and the value of r(to). r(t) = cos( at) i - Intj + Vt-8k; to = 9 Enter the domain in interval notation. Round your answer to two decimal places when needed. Domain is: ? Edit r(to) =
