Each functional equation provides some information about a function or about multiple functions. For example, f ( x ) ? f ( y ) = x ? y f(x)-f(y)=x-y f(x)?f(y)=x?y is a functional equation.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

The equation det (M - xI) = 0 is a polynomial equation in the variable x for given M. It is called the characteristic equation of the matrix M. You can solve it to find the eigenvalues x, of M. The trace of a square matrix M, written as Tr(M), is the sum of its diagonal elements.

Linear Equation Examples: y = 2x + 3. This is a linear equation in the form of y = mx + b. ... 3x ? 2y = 6. This is a linear equation in the form of Ax + By = C. ... 4x + 2y = 8. This is a linear equation in the form of Ax + By = C. ... y = -5x + 2. This is a linear equation in the form of y = mx + b. ... 2x ? 3y = 9.

However, a more restricted meaning is often used, where a functional equation is an equation that relates several values of the same function. For example, the logarithm functions are essentially characterized by the logarithmic functional equation. and the initial value.

Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, ?u + 5v = 9 and 3 = 2 x ? 7y. Note that you can put these equations in the form 1.2s + 3t ? 5 = 0, p + 4q ? 7 = 0, ?u + 5v ? 9 = 0 and 2 x ? 7y ? 3 = 0, respectively.

Examples. 3x + 4y - 7z = 2, -2x + y - z = -6, x - 17z = 4, 4y = 0, and x + y + z = 2 are all linear equations in three variables.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

Double click the dimension, then in the Modify dialog box, type = (equal sign) and several characters of the global variable name. A flyout menu appears with a name that matches the characters you have typed. Both dimensions become linked to the global variable. Repeat for as many dimensions as needed.
