Hello, welcome to this lesson.
00:04
In this lesson we'll use the 5, 10 times to estimate the summation n from 1 to infinity of 1 on 3 plus n to the power 5.
00:16
Okay, essentially we are looking at the estimation to 1 on 3 plus 10 to the power 5.
00:46
Okay, so let's use sl for this.
00:50
Let's have n, then we'd have 3 plus n to the power 5.
00:54
We'll have 1 on 3 plus n to the power 5.
01:00
Okay, so n start from 1 to 10, rounding it to 5 decimal places.
01:18
So here we have 3 plus, let's use power, actually let me use equals to.
01:26
So we'll have 3 plus power, then we'd have, this is the n value, to the power 5.
01:35
Okay, and now we can drag through to fill in for the others.
01:43
The next part, let's have 1 on these answers.
01:50
Okay, so let's also drag through to fill in.
01:57
Alright, and now looking at the summation n from 1 to 10, just as we have done, 1 on 3 plus n to the power 5, actually equals to, let's round this to 5 decimal places.
02:17
So we'll have round, and we are summing.
02:21
So we are summing from this side to that side.
02:27
Okay, then we provide the number of decimal places.
02:31
Okay, and this gives us, so the whole of this gives us 0 .28418.
02:43
And now the second part, we'll look at the arrow...
