A polynomial of degree zero is a constant polynomial or simply a constant.

But the physical meaning can be understood intuitively from the above discussion. The slope essentially tells us, look, start at some point on the line, and go to some other point of the line, measure how much you had to move in the x direction, that is your run, and then measure how much you had to move in the y direction, that is your rise.

Instructional Implications Work with the student on modeling relationships among quantities with equations. In Figure 2, the water wheel rotates in the clockwise direction. To determine if the field is rotating, imagine a water wheel at the point D.

The first term has coefficient 3, indeterminate x, and exponent 2. Ask the student to explicitly describe the meaning of any variables used in the equations. Note that the curl of H is also a vector function. But Vz depends on x. Emphasize the relationship between algebraic expressions and the quantities they represent in the context of the situations in which they arise.

You can add or change the following elements to your equation. The green vector in Figure 4 will try to rotate the water wheel in the clockwise direction, but the black vector will try to rotate the water wheel in the counter-clockwise direction - therefore the green vector and the black vector cancel out and produce no rotation.

For more information, see the partial derivative page. The vector field A is a 3-dimensional vector with x- y- and z- components.

Just choose a structure to insert it and then replace the placeholders, the small dotted-line boxes, with your own values. Only x- and y- directed vectors can cause the wheel to rotate when the wheel is in the x-y plane.

Select Equations in the gallery list. As you can imagine, the curl has x- and y-components as well. But Vz depends on x. I've already used orange, let me use this green color.

Hence, the net effect of all the vectors in Figure 4 is a counter-clockwise rotation. Examples of Student Work at this Level The student writes the correct equation but then: Again, so that the set of objects under consideration be closed under subtraction, a study of trivariate polynomials usually allows bivariate polynomials, and so on.

That is, if we know a vector field then we can evaluate the curl at any point - and the result will be a vector representing the x- y- and z-directions.

Examples of Student Work at this Level The student: We could say b is equal to 8. Hence, the z-directed vector fields can be ignored for determining the z-component of the curl. So that is my y-axis.Note: General Form always has x 2 + y 2 for the first two terms. Going From General Form to Standard Form.

Now imagine we have an equation in General Form. x 2 + y 2 + Ax + By + C = 0. How can we get it into Standard Form like this? (x-a) 2 + (y-b) 2 = r 2 The answer is to Complete the Square (read about that) twice once for x and once for y.

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

The equation 2^(2x-1)= 8^x has to be solved for x. Now, if the base is the same, the exponents can be equated. It is possible to write 8 as a power of 2. 8 = 2^3. In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

An example of a polynomial of a single indeterminate, x, is x 2 − 4x + currclickblog.com example in three variables is x 3 + 2xyz 2 − yz + 1. Improve your math knowledge with free questions in "Slope-intercept form: write an equation from a word problem" and thousands of other math skills.
