All right, hello.
00:01
In this question, we're asked to use the numerical integration feature on a graphing calculator to approximate this value.
00:07
And so i don't know what your graphing calculator is, so i'm going to go ahead and just give a couple options of how to do this.
00:12
On the ti -83 plus or earlier equivalence calculator, there's going to be under the math button, in that first screen that pops up, there will be some function int, which will appear.
00:29
Here.
00:30
And in order to do this on that calculator, you want to do function integrate.
00:34
So this has taken the integral of the function.
00:37
And then you want to put it in the function.
00:39
So f of x, which in this case is 2 ln x, 3 x squared plus 1, comma, that's the, i want to integrate that with respect to x from the lower bound to the upper bound.
00:52
And if you do that, the answer, in case you just want the answer, is going to be to two decimal places 44 .48...
