1. Given A = x^2y.ax — yz.ay + yz^2.az, determine: (a) The magnitude of A at point T(2, -1,3) (b) The distance vector from T to 5 if S is 5.6 units away from T and in the same direction as A at T (c) The position vector of S 3. (a) well for this one just plug in the point T, and solve for A. (b) How do i calculate this point :S?????????????? (c) well once i find the points S then i can just take that point from the origin to it and thats the position vector. Im just confused about b.
