It's a sine function.
So this is going to be a sine function.
I drew the sine function before.
Let's start off with the sine function.
Like the sine function-- we would have a period of pi.
There is the sine, the sine function.
It's just like the sine function was just shifted to the left of it.
So we know that this is a sine function.
And just like the sine function it's oscillating between 1 and negative 1 because on the unit circle you can't get to a point on the perimeter that's higher than that.
So notice, the cosine and the sine functions.
But then, as the sine function becomes greater and the cosine function becomes less, the numerator in the tangent function becomes greater because the numerator is sine. .
Like this program is still tracing the sine function.
And it also oscillates twice as fast as the sine function because it was 0.5 sine of 2x.
But one thing I want to introduce here is the concept of the period or the frequency of the sine function.
And I guess a good place to start is just with the sine function and we can try to graph it.
So let's graph these points out and then we will try to figure out what the points in between look like, and I will show you the graph of a sine function is.
So in order for this to be a valid function-- In order for the inverse sine function to be valid, I have to restrict its range.
That's where we came up with this cosine and sine functions.
So when we're at the angle of pi over 2 radians the sine function is equal to 1.
And notice that this has a period similar to the sine function.
And if you go back to some previous modules you will remember that that's exactly what the sine function was equal to when we looked at the unit circle.
This is more-- This is the inverse sine function.
So to think about that, let's actually draw the sine function out.
Two ways of writing the inverse sine function.
We're asked"what are the domain and range of the sine function?
The SIN() function returns the sine of x, where x is given in radians.
