The magnitude of the vector v, written |v| or v, is the length of the arrow representing v. The standard basis vectors i, j, and k satisfy the following equalities in a right hand coordinate system: × = × = × = which imply, by the anticommutativity of the cross product, that × = − × = − × = − The anticommutativity of the cross product (and the obvious lack of linear independence) also implies that × = × = × = (the zero vector). Furthermore, a normal vector points towards the center of curvature, and the derivative of tangent vector also points towards the center of curvature. The diagram works by using the 20° angle and creating a right triangle within the circle as shown below. Express the work in terms of the dot product between the force and the displacement vectors.

If u is a new coordinate vector given in terms of the old set then comp uw gives the component of the vector w in the new coordinate system. Assuming the D J (λ) (k ⊥) are reasonably well-clustered around 〈D〉, all terms D J (λ) (k ⊥)/〈D〉 will lie on the same branch of the logarithm. The case where k = 1 is trivial. (See also the package on Divergence and Curl. The demo also has the ability to plot 3 other vectors which can be computed from the first two input vectors. BASIS AND DIMENSION OF A VECTOR SPACE 135 4. If you imagine a graph with the x and y axis being at right angles to each other and having a third, z axis coming out of the page, then a triplet of numbers, (X, Y, Z) would represent a point in the region, and a vector from the origin to the point. Thus the equation of the plane is x y 2z 0. The value of each component is equal to the cosine of the angle formed by the unit vector—with the respective basis vector. A third vector C lies in the xy-plane. Since you said i, j, and k were the vector components, I removed them from the equation and used t for x(t), 2t for y(t), and t 2 for z(t) and got this (input here). Exercise 1.
