We trust you find the Supplement a useful teaching tool. Contents 1 Vectors 3 1. Recall the notation that [a, b] denotes a move of a units horizontally and b units vertically. During the second part of the walk, the hiker walks a distance of 5 km northeast.
Plots of all three vectors are 2. Plots of all three vectors are. Then, as the diagonal of the parallelogram, the resultant vector is 0. The second figure illustrates this, linear algebra a modern introduction 4th edition pdf download. No solution. But 4 times anything is even, so it cannot leave a remainder of 3 when divided by 6 which is also even. Following Example 1. Finding a unit vector v in the same direction as a given vector u is called normalizing the vector u.
Proceed as in Example 1. Thus the angle between u and v is a right angle. As in Example 1. To show that OAB C is right, we need only show that one pair of its sides meets at a right angle.
It is unnecessary to test the remaining pairs of sides. It is unnecessary to test the remaining pair of sides. Since the cube is symmetric, we need only consider one diagonal and adjacent edge. Orient the cube as shown in Figure 1. Since the cube is symmetric, we need only consider one pair of diagonals.
Since the dot product is nonzero, linear algebra a modern introduction 4th edition pdf download, the diagonals are not orthogonal. To show a parallelogram is a rhombus, it suffices to show that its diagonals are perpendicular Euclid. To determine its side length, note that since the diagonals are perpendicular, one half of each diagonal are the legs of a right triangle whose hypotenuse is one side of the rhombus.
So we can use the Pythagorean Theorem. Let the x direction be east, in the direction of the current, and the y direction be north, linear algebra a modern introduction 4th edition pdf download, across the river. Let the x direction be the direction across the river, and the y direction be downstream. Therefore a Ann lands 0.
Note that the river flow does not increase the time required to cross the river, since its velocity is perpendicular to the direction of travel.
A graph of the situation is with proj u v in gray, and the perpendicular from v to the projection also drawn. A graph of the situation is with proj u v in gray, and the perpendicular from v to the projection also drawn 2.
The geometry of the vectors in Figure 1. This means that the angle between them must be 0. So we first prove Lemma 1. First assume that u and v point in the same direction. Using the lemma again shows that u and v point in the same direction. This entire proof is exactly analogous to the proof in part a.
We first prove Lemma 3. We can now show Theorem 4. Next, linear algebra a modern introduction 4th edition pdf download, we can square both sides of the equality, so that 2. Using the lemma again shows that u and v point in opposite directions. Prove Theorem 1. Prove the three parts of Theorem 1. So if the dot product is to be zero, each u2 must be zero, which means i. Then by Theorem 1. This follows immediately from Theorem 1.
Then 2. From Example 1. From Theorem 1. We have. But the final expression is nonnegative since it is a square. But the final expression is nonnegative since it is the sum of three squares. Thus these u. Let v1, v2. Use the notation that the vector OX is written x. Draw AC. Also draw BD. Thus opposite sides of the quadrilateral P QRS are equal. In a like manner, we see that P S"RQ.
Thus P QRS is a parallelogram. Following the hint, we find m, the point that is two-thirds of the distance from A to P. From exercise linear algebra a modern introduction 4th edition pdf download, we have. Again from exercise 1, we have. Thus all the altitudes intersect at the orthocenter H. Thus RK 2. Let O, the center of the circle, be the origin.
We want to show that AC is orthogonal to BC. As in exercise 5, we first find m, the point that is halfway from P to R. Similarly, we find mj, the point that is halfway from Q to S. Any pair of points on A determine a direction vector, so we use P and Linear algebra a modern introduction 4th edition pdf download. We must find two direction vectors, u and v. Since u and v are linear algebra a modern introduction 4th edition pdf download scalar multiples of each other, they will serve as direction vectors if they were parallel to each other, we would have not a plane but a line.
This is true in general. So as t varies from 0 to 1, the line describes the line segment P Q. Similarly, the vector whose head is 2 of the way from P to 3.
Now, A1 and A2 are perpendicular if and only if their normal 1 vectors are perpendicular, i. Suppose the line A has direction vector d, and the plane P has normal vector n. A is parallel to P. A is perpendicular to P.
Suppose the plane P1 has normal vector n1and the plane P has normal vector n. P1 is parallel to P. A line is perpendicular to a plane if its direction vector d is the normal vector n of the plane. Note that a plane is parallel to a given plane if their normal vectors are equal. Using Figure 1. Now consider P4, the plane containing the face parallel to the face in the yz-plane but passing 1 through 1, 1, 1.
Since P is perpendicular to the z xy-plane, their normal vectors must be orthogonal. But the normal vector is also 0 perpendicular to the plane in question, by definition.
