What's the important part of each one of these is not only what the areas are, but the location is.
00:10
And what i'm talking about is being above the x -axis, below the x -axis, and things like that.
00:15
Because any time that you are below the x -axis, i'm not going to make it as good.
00:22
Yes, the area is a positive number.
00:26
But anytime you're below, that's got to be a negative value.
00:31
As far as the integral goes.
00:33
So the next few pieces being above my picture is not drawn to scale at all, 11 and 21.
00:44
But the fact that they are above the x -axis, those two would be positive values.
00:50
So kind of jumping into letter a, i think it's a lot of going from 0 to 1 of f of x, dx, that that answer would be negative 59...
