In the question, we are given with the integral that is integration of under root 4 plus x cube dx.
00:08
Limit is from 0 to 6 and we have n is equal to 4.
00:13
So, here we have a is equal to 0 and we have b is equal to 6.
00:21
So, if we will find width, so this will be equal to delta x will be equal to b minus a upon n.
00:28
So this will be equal to 6 minus 0 upon 4 which is equal to 3 upon 2 and 3 upon 2 is 1 .5.
00:36
So therefore the end points are the end points are x 0 will be equal to a and this will be equal to 0 and we will have x 1 will be equal to x 0 plus delta x.
00:58
So this is equal to 1 .5 and we will have x2 is equal to x1 plus delta x.
01:09
So this will be equal to 3 and we will have x3 will be equal to x2 plus delta x.
01:18
So this will be equal to 4 .5 and we have x4 is equal to x3 plus delta x.
01:27
So this will be equal to 6 then if you will find f of x 0 so this will be under root of 4 plus 0 cube so this is equal to 2 and if you will find f of x 1 so this will be equal to under root of 4 plus 1 .5 cube so this is equal to 2 .715695 and if you will find f of x 2 so this this will be equal to under root of 4 plus 3 cube.
02:02
So this will be equal to 5 .56776.
02:10
And if you will find f of x3.
02:12
So this will be equal to under root of 4 plus 4 .5 whole cube...
