Hi, i'm david and i'm here to have you answer your question.
00:04
Now let me bring up your question here.
00:08
In this question here we want to discuss about the left remand sum to compute the area.
00:15
Now let me show you how to do it.
00:21
Here we are given the function fx equal to 1 over x minus 1.
00:29
That would be something i see here.
00:31
So we have the 1 minus x will be something like a banker here.
00:37
This will be 1 over x.
00:40
And then we have 2 minus 1, so we have to sit this one down.
00:43
So by one unit.
00:45
Therefore, the graph would like something like this.
00:51
And then this one will be something down here.
00:58
That will be the graph from the 1 of x minus 1.
01:02
Now we will consider the interval from 3 to the 4.
01:08
So from 3 it will be, this will be the 3, this will be the 4, so let me make it bigger.
01:16
I will scale it differently, so this and 3, this will be 4, something like that.
01:21
And then we want to use the nl4, so it means that the n here it will equal to 4.
01:30
So we have to split it into the 4 intervals...
