# Rewrite as single logarithm worksheets

Help Keep the Winemaking Home Page a Free Websitea self-serving plea for support October 24th, I have not written anything here in a long time. Most recently, my health took a turn for the worse and a full diagnosis is still pending. Let us consider float division first. We consider those in the next section. For a complete listing of the functions available, see http: We begin with the simplest functions. First, we need to consider how to create our own functions.

Next, we learn how to express this equation as a new function, which we can call with different values. Before we get to solving equations, we have a few more details to consider. Next, we consider evaluating functions on arrays of values. We often need to make functions in our codes to do things.

That is why we see the error above. There are a few ways to achieve that. One is to "cast" the input variables to objects that support vectorized operations, such as numpy. The syntax is lambda var: I think these are hard to read and discourage their use.

Here is a typical usage where you have to define a simple function that is passed to another function, e.

You might do this so you can integrate the wrapped function, which depends on only a single variable, whereas the original function depends on two variables. You can create default values for variables, have optional variables and optional keyword variables. In this function f a,ba and b are called positional arguments, and they are required, and must be provided in the same order as the function defines.

If we provide a default value for an argument, then the argument is called a keyword argument, and it becomes optional. You can combine positional arguments and keyword arguments, but positional arguments must come first.

Here is an example. In the second call, we define a and n, in the order they are defined in the function. Finally, in the third call, we define a as a positional argument, and n as a keyword argument.

If all of the arguments are optional, we can even call the function with no arguments. If you give arguments as positional arguments, they are used in the order defined in the function. If you use keyword arguments, the order is arbitrary. Suppose we want a function that can take an arbitrary number of positional arguments and return the sum of all the arguments. Inside the function the variable args is a tuple containing all of the arguments passed to the function.

This is an advanced approach that is less readable to new users, but more compact and likely more efficient for large numbers of arguments.

This is a common pattern when you call another function within your function that takes keyword arguments. Inside the function, kwargs is variable containing a dictionary of the keywords and values passed in. Provide kwargs to plot.Logarithm worksheets in this page cover the skills based on converting between logarithmic form and exponential form, evaluating logarithmic expressions, finding the value of the variable to make the equation correct, solving logarithmic equations, single logarithm, expanding logarithm using power rule, product rule and quotient rule, expressing the log value in algebraic expression.
