All the tools & learning materials you need for study success - in one app.
Get started for freeSketch the vector \(v\) and write its component form. \(\mathbf{v}\) lies in the \(x z\) -plane, has magnitude \(5,\) and makes an angle of \(45^{\circ}\) with the positive \(z\) -axis.
Determine which of the vectors is (are) parallel to \(\mathrm{z}\). Use a graphing utility to confirm your results. \(\mathbf{z}=\frac{1}{2} \mathbf{i}-\frac{2}{3} \mathbf{j}+\frac{3}{4} \mathbf{k}\) (a) \(6 \mathbf{i}-4 \mathbf{j}+9 \mathbf{k}\) (b) \(-\mathbf{i}+\frac{4}{3} \mathbf{j}-\frac{3}{2} \mathbf{k}\) (c) \(12 \mathbf{i}+9 \mathbf{k}\) (d) \(\frac{3}{4} \mathbf{i}-\mathbf{j}+\frac{9}{8} \mathbf{k}\)
Find the direction angles of the vector. $$ \mathbf{u}=\langle-2,6,1\rangle $$
In Exercises 49 and \(50,\) find each scalar multiple of \(v\) and sketch its graph. \(\mathbf{v}=\langle 1,2,2\rangle\) (a) \(2 \mathbf{v}\) (b) \(-\mathbf{v}\) (c) \(\frac{3}{2} \mathbf{v}\) (d) \(0 \mathbf{v}\)
Find the component form and magnitude of the vector \(u\) with the given initial and terminal points. Then find a unit vector in the direction of \(\mathbf{u}\). \(\frac{\text { Initial Point }}{(1,-2,4)}\) \(\frac{\text { Terminal Point }}{(2,4,-2)}\)
