Here is the warning admon:

Division by zero is illegal!Most math systems will give fatal errors if you divide by zero.

```
Terminal> python -c 'print 4/0'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
```

You should therefore be very careful with all expressions that may result in division by zero. In Python, you can use a

`try-except`

clause to test if some expression gives a`ZeroDivisionError`

exception and take appropriate actions. One example of a numerical method where division by zero can cause problems is Newton's methods of finding solutions to algebraic equations $f(x)=0$. In that algorithm, there is a division by $f'(x)$.

Question admon (without title).

?

Summary admon:

Summary.The most popular methods for solving algebraic equations

$$
f(x) = 0
$$

are

Newton's method

The Bisection method

The Secant method

The Fixed-Point method ($f(x) = x - g(x)$)

Of these, Newton's method is fastest, the Bisection method is the most reliable, the Secant method is a simplified Newton method, and the Fixed-Point method is obviously very problem dependent in its behavior since the user has the define the $g$ function.

Here is a *notice admon*:

Tip: follow well-established conventions for variable names!For example, in Python, variable and function names use lower case letters separated by underscore, as in

`vibration_with_damping`

(while Java typically would have`vibrationWithDamping`

). Class names apply cap words, as in`ProblemClass`

.

The four main admons are warning, notice, question, and summary.

DocOnce features a `block`

environment with or without title.

Blocks are often used in slides to frame a collection of things.

Block with title.Blocks can contain text, math, code, figures, movies.

Here is a quote environment (`quote`

):

Sayre's law states that "in any dispute the intensity of feeling is inversely proportional to the value of the issues at stake." By way of corollary, it adds: "That is why academic politics are so bitter."
