Im doing a question where I have to graphc y = -4 sin x

Ok well I got the period and amplitude, so I have the interval of [0, 2pi]

Now, in order to plot points, I have to divide the interval into 4 sub intervals.

I dont understand how I do that! This is where I get stuck, and dont know how to plot the points now.

Any help would be great!

2. Relevant equations

3. The attempt at a solution

In my book it says " We divide the interval [0, 2pi] into 4 sub intervals, each of length 2pi/4 = pi/2

I dont get that.
