QUESTION Consider P4 be a set of all the point on a plane through the origin in R4. The general equation of a plane through the origin in R4 as follow aw+bx+cy + dz = 0 where a, b, c, and d are fixed constant and at least one is not zero. Show that P4 with the standard addition and scalar multiplication is a vector space.
Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These families appear commonly in the solution of differential equations. When a constant of integration is added, it is normally modified algebraically until it no longer replicates a plain linear transformation. The order of a differential equation depends on how many uncertain variables appear in the corresponding curve. The order of the differential equation acquired is two if two unknown variables exist in an equation belonging to this family.
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are real numbers and a is the horizontal coordinate and b is the vertical coordinate. This type of plane is called two-dimensional and it contains two perpendicular axes, the horizontal axis, and the vertical axis.
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) geometry was introduced by the Greek mathematician Euclid, and that is why it is called Euclidean geometry. Euclid explained this in his book named 'elements'. Euclid's method in Euclidean geometry involves handling a small group of innately captivate axioms and incorporating many of these other propositions. The elements written by Euclid are the fundamentals for the study of geometry from a modern mathematical perspective. Elements comprise Euclidean theories, postulates, axioms, construction, and mathematical proofs of propositions.
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
Clues
1. Create 3 equations that follow the form aw + bx + cy + dz = 0. Label each equation, for example E1, E2, E3. Each equation represents three different points on the plane in R^4 through the origin. Example: E1: 2a + 3b - 4c + 5d = 0, E2: -1a +6b + 7c - 10dz = 0, E3: a-b+c-d=0.
2. Also, assume two scalars, e.g., k = 5, l = -3.
3. Then, use any two of the three equations to show that Axioms 1 and 6 holds.
4. Axiom 1: u + v is in V. Since I denote the equations as E1, E2 and E3, then for axiom 1 to hold, E1 + E2 must produce an equation also of the form aw + bx + cy + dz = 0. In other words, for axiom 1 to hold, E1 + E2 is in P4.
5. Adding E1 and E2 will give us a + 9b + 3c - 5d = 0. Obviously, this new equation follows the form aw + bx + cy + dz = 0. So, axiom 1 holds.
6. Then you show axiom 6 holds using any one of the three equations and any one of the two scalars, e.g., kE1 = 5E1 = 10a + 15b – 20c + 25d = 0.
7. Then, proceed to show the remaining 8 axioms also hold using the equations that you have created and the scalars that you have assumed.
