1
00:00:00,370 --> 00:00:05,960
Yes, and welcome back to another class of our course about the complete introduction to that science

2
00:00:06,570 --> 00:00:07,330
show in this class.

3
00:00:07,350 --> 00:00:13,920
I thought that it would be great to have a little bunnies and to add to functions that can work with

4
00:00:13,920 --> 00:00:15,150
numpty as well.

5
00:00:15,420 --> 00:00:21,780
So basically, I just wanted to show you at first all the operations that are that we can do on Python.

6
00:00:22,320 --> 00:00:28,740
But I thought that adding to more functions could be a good thing and at the same time, you guys will

7
00:00:28,740 --> 00:00:29,760
probably love it.

8
00:00:30,210 --> 00:00:35,040
So basically, the two functions that we are going to talk about today would be the exponential function

9
00:00:35,310 --> 00:00:40,500
or at Exponent X and the logarithmic function.

10
00:00:40,710 --> 00:00:48,240
And basically the goal today is just to show you that number is able to well, to make errors and make

11
00:00:48,390 --> 00:00:50,480
those functions work with Eriks.

12
00:00:50,820 --> 00:00:53,500
So basically apply functions on those areas.

13
00:00:54,000 --> 00:00:56,810
So it's pretty it's not something that is too complicated to do.

14
00:00:57,480 --> 00:00:59,760
And at the same time, it's pretty cool.

15
00:01:00,000 --> 00:01:01,470
Well, I mean, at least.

16
00:01:01,860 --> 00:01:02,130
All right.

17
00:01:02,190 --> 00:01:05,250
So the first thing that we will do is pretty simple.

18
00:01:05,400 --> 00:01:07,270
We need to write down our area.

19
00:01:07,290 --> 00:01:16,650
So basically our variables in this case are one would be our variable like always and our variable basically

20
00:01:16,650 --> 00:01:17,430
what we'll do with it.

21
00:01:17,430 --> 00:01:21,090
We will create an area so empty that every.

22
00:01:22,840 --> 00:01:28,620
We open up our apprentices, and in this case, we'll work with just a one dimensional.

23
00:01:29,350 --> 00:01:30,300
So pretty simple.

24
00:01:30,640 --> 00:01:32,190
So like always will use it.

25
00:01:32,210 --> 00:01:35,210
Well, we'll use some other numbers for three, six and nine.

26
00:01:36,640 --> 00:01:38,470
And right now, we have our own.

27
00:01:38,860 --> 00:01:42,280
So the next step is pretty simple, is writing down our functions.

28
00:01:42,460 --> 00:01:50,530
And what's going to happen is that Python will just apply those functions on each number inside of our

29
00:01:50,530 --> 00:01:50,830
own.

30
00:01:51,190 --> 00:01:55,320
So the first function that we are going to have will be the exponential function.

31
00:01:55,600 --> 00:01:58,560
And basically how this function works is pretty simple.

32
00:01:58,840 --> 00:02:03,880
So it's simply EA or two point seven two and some other numbers.

33
00:02:04,120 --> 00:02:05,020
I don't remember them.

34
00:02:05,800 --> 00:02:07,750
Exponent are a number.

35
00:02:07,990 --> 00:02:11,110
So basically if we try it out, so simply write down.

36
00:02:13,060 --> 00:02:14,320
And so, Brent.

37
00:02:18,620 --> 00:02:20,760
And people that likes me.

38
00:02:23,960 --> 00:02:30,500
And in this case, we are one, so basically what I have just done is I wrote my print function, so

39
00:02:30,500 --> 00:02:35,480
I asked Python to print the exponential function of this variable right here.

40
00:02:35,840 --> 00:02:40,490
So basically, since we have an array, what is going to happen is going to apply the exponential function

41
00:02:40,850 --> 00:02:42,830
on all the numbers right here.

42
00:02:42,860 --> 00:02:48,020
So basically the exponential function on this number, this one and this one, and if we can see it

43
00:02:48,020 --> 00:02:48,470
right here.

44
00:02:48,500 --> 00:02:50,020
So basically for the first one.

45
00:02:50,030 --> 00:02:54,110
So basically for the tree, it's going to be this for the six, it's going to be this.

46
00:02:54,110 --> 00:02:55,430
And for the night it's going to be this.

47
00:02:56,600 --> 00:03:00,480
It works pretty much the same way if you want to have a logarithmic function.

48
00:03:00,770 --> 00:03:05,450
So basically, the log function is simply the reverse of the exponential function.

49
00:03:07,280 --> 00:03:10,620
It's not a log and usually it's locked in this case, not a lectern.

50
00:03:10,970 --> 00:03:16,910
So if we try it out, the only thing that you guys have to do is simply exchanged exponential function

51
00:03:17,300 --> 00:03:18,850
by a log function.

52
00:03:18,860 --> 00:03:22,130
So simply change the Peabody Energy.

53
00:03:22,130 --> 00:03:25,460
So a logarithmic function and you can run the app.

54
00:03:25,580 --> 00:03:31,020
And as you can see, you will have the complete well, you will have those answers right here.

55
00:03:31,970 --> 00:03:35,740
So basically, as I said, it's simply the reverse of the exponential function.

56
00:03:35,840 --> 00:03:39,620
So I'm not going to give you guys a complete mathematical course about all this.

57
00:03:40,520 --> 00:03:43,950
But once again, it's well, it's pretty well, it's pretty cool.

58
00:03:45,170 --> 00:03:50,570
Usually it's possible to show it on a graph, but I won't do it because I will need to use matplotlib

59
00:03:50,570 --> 00:03:51,110
for it.

60
00:03:51,170 --> 00:03:56,210
That's the visualization tool and will work with it a bit later in this class.

61
00:03:56,220 --> 00:04:02,450
So you'll see a bit later in the scores will work with different tools that will let us visualize our

62
00:04:02,450 --> 00:04:04,820
data or put everything on graphs.

63
00:04:05,240 --> 00:04:05,540
All right.

64
00:04:05,550 --> 00:04:11,090
So now you guys know how to work with exponential functions as well as logarithmic functions inside

65
00:04:11,090 --> 00:04:14,150
of Python with no bite you can work with?

66
00:04:14,960 --> 00:04:20,660
Well, there are plenty of other functions with which you can work using IRI's, and those are pretty

67
00:04:20,660 --> 00:04:20,960
cool.

68
00:04:21,560 --> 00:04:23,130
So that's it for this part of the course.

69
00:04:23,150 --> 00:04:29,690
Guys, I hope you guys, like nonpaying, learned a lot of things about it and see you in the next part

70
00:04:29,690 --> 00:04:30,500
of this.
