# How to write an equations for a step function

We will assign a number to a line, which we call slope, that will give us a measure of the "steepness" or "direction" of the line. It is often convenient to use a special notation to distinguish between the rectan- gular coordinates of two different points. We can designate one pair of coordinates by x1, y1 read "x sub one, y sub one"associated with a point P1, and a second pair of coordinates by x2, y2associated with a second point P2, as shown in Figure 7. Note in Figure 7. O should be images. If works in Math. SE why not here? Maybe can screw the things As you've discovered, the TeX. This is a deliberate choice as most users of the TeX. SE site will be far more interested in seeing the underlying code rather than its visual appearance after it's been processed.

If you need to show the result of some code, you can always compile it best with the standalone document class and then upload it as an image -- like I did in two instances in the answer I wrote. A partial answer, though, is that in Mico's answer below you can replace ll by whatever you want - cl sounds like it might suit?

Note that it's only necessary to have one array, rather than two nested array environments.

As you can tell from the image, the spacing between lines is rather tight, because of the fraction terms in the first column. If you think this is a problem, you can always add a bit of extra vertical space by appending [0. These options to the "newline" commands instruct TeX how much extra space to insert.

The result of adding the extra vertical spacing will look like this:So now this is the delta function.

The delta function runs along at 0, continues at 0, but at t at 0, the whole thing explodes. The derivative is infinite. You see an infinite slope there. And the point is infinity is not a sufficiently precise word to tell you exactly what's happening. So we don't have really--this graph of a delta function is not fully satisfactory. It's perfect for all the uninteresting boring part.

How to Solve Quadratic Equations. A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2.

There are three main ways to solve quadratic equations: 1) to factor the quadratic. A step function (or staircase function) is a piecewise function containing all constant "pieces".

The constant pieces are observed across the adjacent intervals of the function, as they change value from one interval to the next. A step function is discontinuous (not continuous). Solving Quadratic Equations Terminology. 1. A Quadratic equations is an equation that contains a second-degree term and no term of a higher degree.
