00:00:05,000 --> 00:00:06,000
Hello friends.

2
00:00:06,000 --> 00:00:11,000
Today I will tell you how to use formula node for creating a.

3
00:00:12,000 --> 00:00:17,000
Sine wave or a waveform, not particularly sine wave.

4
00:00:19,000 --> 00:00:19,000
Order.

5
00:00:20,000 --> 00:00:21,000
Mathematical function.

6
00:00:21,000 --> 00:00:24,000
That is a combination of two functions.

7
00:00:25,000 --> 00:00:30,000
So first I just go to for loop because I need some points.

8
00:00:31,000 --> 00:00:33,000
To create constant over here.

9
00:00:33,000 --> 00:00:37,000
Let's say I want to just generate 300 points.

10
00:00:38,000 --> 00:00:39,000
For formula node.

11
00:00:39,000 --> 00:00:41,000
Just go to structures.

12
00:00:41,000 --> 00:00:43,000
Select your.

13
00:00:44,000 --> 00:00:45,000
One node.

14
00:00:46,000 --> 00:00:48,000
Or here, I'm just using.

15
00:00:49,000 --> 00:00:52,000
A variable A that is equal to.

16
00:00:54,000 --> 00:00:54,000
Ten.

17
00:00:56,000 --> 00:00:59,000
All X plus.

18
00:01:00,000 --> 00:01:02,000
Cause of.

19
00:01:04,000 --> 00:01:06,000
X plus.

20
00:01:08,000 --> 00:01:09,000
Sign of.

21
00:01:10,000 --> 00:01:12,000
X, let's say.

22
00:01:12,000 --> 00:01:16,000
Just put a semicolon after it over here.

23
00:01:16,000 --> 00:01:18,000
Just add input.

24
00:01:18,000 --> 00:01:23,000
My input is x variable and the output is.

25
00:01:24,000 --> 00:01:24,000
Capital.

26
00:01:26,000 --> 00:01:28,000
So just connect.

27
00:01:29,000 --> 00:01:33,000
EC2 the system or here.

28
00:01:33,000 --> 00:01:40,000
My input is I want to just need maximum points.

29
00:01:40,000 --> 00:01:44,000
So I just divide this value with ten.

30
00:01:44,000 --> 00:01:48,000
Right now this is my function a and.

31
00:01:49,000 --> 00:01:53,000
I have another variable that is B that is equal to.

32
00:01:55,000 --> 00:01:56,000
It is a.

33
00:01:57,000 --> 00:01:58,000
Cube.

34
00:01:59,000 --> 00:02:00,000
Plus.

35
00:02:02,000 --> 00:02:05,000
Hey, I want to just plot this function also.

36
00:02:07,000 --> 00:02:12,000
So just put semicolon add output.

37
00:02:16,000 --> 00:02:18,000
Be is my another function.

38
00:02:19,000 --> 00:02:21,000
Just connect it to the edge.

39
00:02:21,000 --> 00:02:22,000
Just.

40
00:02:23,000 --> 00:02:26,000
Drag and drop a waveform graph over here.

41
00:02:28,000 --> 00:02:29,000
As you see.

42
00:02:31,000 --> 00:02:34,000
In this case, just go to the build array function.

43
00:02:37,000 --> 00:02:38,000
In the build array function.

44
00:02:39,000 --> 00:02:40,000
Just connect over here.

45
00:02:40,000 --> 00:02:42,000
This is my function A this is my function.

46
00:02:42,000 --> 00:02:44,000
B Just connect it.

47
00:02:45,000 --> 00:02:46,000
Run it.

48
00:02:46,000 --> 00:02:50,000
As you see over here, you got the signal.

49
00:02:51,000 --> 00:02:53,000
If I just remove.

50
00:02:55,000 --> 00:02:58,000
The sine function from here.

51
00:02:58,000 --> 00:02:59,000
Let's check what happened to it.

52
00:03:01,000 --> 00:03:02,000
As you see.

53
00:03:05,000 --> 00:03:09,000
So this is nearly a increasing graph.

54
00:03:09,000 --> 00:03:13,000
I'm just removing this part from the graph.

55
00:03:14,000 --> 00:03:15,000
Control be.

56
00:03:16,000 --> 00:03:18,000
Just minimize it.

57
00:03:18,000 --> 00:03:20,000
So when I hit on run button.

58
00:03:21,000 --> 00:03:27,000
So this is my graph, as you see from here right now.

59
00:03:27,000 --> 00:03:27,000
It is.

60
00:03:29,000 --> 00:03:30,000
Increasing.

61
00:03:30,000 --> 00:03:38,000
And over here, let's say I'm just changing the function to a four plus A In this case, you just check.

62
00:03:39,000 --> 00:03:41,000
What happened to the function?

63
00:03:42,000 --> 00:03:46,000
And in the place of X, I am just putting.

64
00:03:48,000 --> 00:03:49,000
X square over here.

65
00:03:52,000 --> 00:03:55,000
Let's check what happened to the single signal.

66
00:03:57,000 --> 00:04:08,000
So this is how you can use formula node to create any signal in place, of course, of x and just hyperbolic

67
00:04:08,000 --> 00:04:08,000
function.

68
00:04:08,000 --> 00:04:11,000
I'm just using, as you see right now.

69
00:04:16,000 --> 00:04:17,000
Check the signal.

70
00:04:18,000 --> 00:04:21,000
If I just make it sign?

71
00:04:23,000 --> 00:04:24,000
Let's check what happened to it.

72
00:04:26,000 --> 00:04:30,000
So this is how you can use formula node.

73
00:04:31,000 --> 00:04:33,000
For the creation of the faint signals.

74
00:04:34,000 --> 00:04:37,000
In this case, there is no need of this build function.

75
00:04:37,000 --> 00:04:43,000
You can just directly connect it to your waveform graph also.

76
00:04:43,000 --> 00:04:44,000
Thank you.
