So let us start with the concept which we are going to use here for this question.
00:07
For the given integral we have to find the error.
00:10
So since we know that the relative error that can be defined by the estimated value minus of the actual value that whole divided by the actual value and in percentage we should multiply it by 100.
00:39
So for that we have been given in a part integration t is equals to 1 to 5 t square plus 1 of dt.
00:50
So first of all let us find its left end points.
00:55
So what will be the left end points? so it is varying from 1 to t equals to 5 so t cube by 3.
01:03
So that means it will comes out equals to 34.
01:07
Similarly the right end points that can be 58.
01:15
Now if you try to find the midpoints so it can be 45 then trapezoidal so trapezoidal points will be 46 and simpsons will comes to 45 .3333.
01:32
So there's all are nothing but the approximations.
01:36
So by using the second derivative the actual value actual value can be calculated double integration of t 1 to 5 t square plus 1 dt.
01:54
So this will be goes to now integration of t square will be t cube by 3 plus integration of 1 will be t and the limits will go from 1 to 5...
