16 Νοε 2022 · Basic Concepts – In this section we will introduce some common notation for vectors as well as some of the basic concepts about vectors such as the magnitude of a vector and unit vectors. We also illustrate how to find a vector from its starting and end points.
Vector Calculus Solutions to Sample Final Examination #1 1. Let f(x;y)=exysin(x+ y). (a) In what direction, starting at (0;ˇ=2), is fchanging the fastest? (b) In what directions starting at (0;ˇ=2) is fchanging at 50% of its maximum rate? (c) Let c(t) be a flow line of F = rfwith c(0) = (0;ˇ=2). Calculate d dt [f(c(t))] t=0: Solution
Vector calculus Solutions to exercises in appendix C of the notes. Exercise C.1. (Exercise 4 in assignment 1 of MA2VC 2013–14.) Show that, for any unit vector ˆn, and any vector w perpendicular to ˆn, the identity. ˆn × (ˆn × w) = −w.
Problem 5.17. (1) Show that any continuous function on [0; 1] is the uniform limit on [0; 1) of a sequence of step functions. Hint:- Reduce to the real case, divide the interval into 2n equal pieces and de ne the step functions to take in mim of the continuous function on the corresponding interval.
Calculus II Practice Problems 1: Answers 1. Solve for x: a) 6x 362 x Answer. Since 36 62, the equation becomes 6x 62 2 x, so we must have x 2 2 x which has the solution x 4 3. b) ln3 x 5 Answer. If we exponentiate both sides we get x 35 243. c) ln2 x 1 ln2 x 1 ln2 8 Answer. Since the difference of logarithms is the logarithm of the quotient, we ...
EXAMPLE 2 The vector field R/r consists of unit vectors u,, pointing outward. We divide R = xi + yj by its length, at every point except the origin. The components of Rlr are M = xlr and N = y/r. Figure 15.1 shows a third field ~/r~, whose length is 1 /r. Fig. 15.1 The vector fields R and R/r and R/r2 are radial. Lengths r and 1 and l/r
