So what the cumulative distribution function is essentially let me call it the cumulative distribution function it's a function of x.

But if they map to a one dimensional space, we call them a scalar valued function, or a real valued function.

You give a function an input, let's call that input x, right?

I think that's why they call it a transformation as opposed to a function.

So I'll call that m, the function will be m, and it's a function of how many tickets he sells.

So what I want to do is define a remainder function, or sometimes I've seen textbooks call it an error function.

Insert a function

I'm a function.

The first one I guess it's really just one function, I said it's a couple but I'll call it the identity function.

Say we have a function, let me define a function.

So the period of this periodic function because that's what we call a function that keeps repeating, the period of this periodic function is this distance from here to here.

This is a function.

It is a function.

It's really a function.

That is a function.

It's a sine function.

It's a constant function.

Instead of a function x and y, if I could rewrite this differential equation so that dy dx is equal to some function, let's call that G, or we'll call it capital F.

It's a function of u, and it is a function of v.

Let's say it's equal to some function of x, we'll call that f1 of x, times some function of y.

And that's a function of a.

We have a function of x, we have a function purely of x.

That's when a function can be a function of more than one variable.

That's a pretty straightforward function.

I, I'm just a function.

It's just a constant function.

This is not a function.

This is a scalar function.

That's all a function is.

I'll have a general function.

So let me draw a function here actually, let me define a function here.

But a function is just a rule.

So part a is definitely a function.

So let's say Dustin charges, so the function, I'll call it d for Dustin.

What does the inverse function look like, as a function of x?
