Hello friends.

2
00:00:11,000 --> 00:00:19,000
Today we discuss about expression node in detail, so just go to numeric.

3
00:00:22,000 --> 00:00:26,000
Over here we have expression, not just put it.

4
00:00:26,000 --> 00:00:32,000
So just go for select this Ctrl h.

5
00:00:32,000 --> 00:00:38,000
It will show you different operations performed by this expression node.

6
00:00:38,000 --> 00:00:45,000
So as you see over here, this is my input two plus x into log of x, it will give you the output.

7
00:00:46,000 --> 00:00:54,000
The following built in functions are allowed allowed in formulas like if you want to find out the sine

8
00:00:54,000 --> 00:01:06,000
cosine for quote cos exponential log, natural log maximum minimum of something if you want to find

9
00:01:06,000 --> 00:01:12,000
out the size square root ten etcetera, you can use expression node.

10
00:01:12,000 --> 00:01:14,000
So let's check.

11
00:01:14,000 --> 00:01:18,000
So first I just go with sine of x.

12
00:01:19,000 --> 00:01:20,000
So sine of.

13
00:01:22,000 --> 00:01:23,000
X into.

14
00:01:25,000 --> 00:01:31,000
Another function is let's say cos of square cos of X square.

15
00:01:31,000 --> 00:01:44,000
So X into X and into let us say I want to again multiply it with sine of x cube.

16
00:01:45,000 --> 00:01:49,000
So x into x into x.

17
00:01:49,000 --> 00:01:56,000
So it will give me the output of sine x into cos x square into cosine x cube.

18
00:01:57,000 --> 00:02:01,000
So let's put the value create control over here.

19
00:02:03,000 --> 00:02:03,000
It is.

20
00:02:03,000 --> 00:02:07,000
It is my ex that is my variable.

21
00:02:07,000 --> 00:02:11,000
And over here, this is my output of this function.

22
00:02:11,000 --> 00:02:16,000
So let's check the output if X is zero.

23
00:02:16,000 --> 00:02:20,000
In this case, the output should be zero because sine zero is zero.

24
00:02:20,000 --> 00:02:22,000
Let's run it.

25
00:02:22,000 --> 00:02:24,000
So as you see, it is zero.

26
00:02:24,000 --> 00:02:27,000
If you put one over here.

27
00:02:28,000 --> 00:02:29,000
X is one.

28
00:02:29,000 --> 00:02:32,000
In this case, the output is 0.38.

29
00:02:32,000 --> 00:02:36,000
If you want to increase the size, you can also increase the size.

30
00:02:36,000 --> 00:02:37,000
Let's.

31
00:02:38,000 --> 00:02:40,000
Check on here.

32
00:02:41,000 --> 00:02:42,000
As you see.

33
00:02:42,000 --> 00:02:47,000
So this is how you can find out if you want to go for for multiple values.

34
00:02:47,000 --> 00:02:50,000
So just increase this one.

35
00:02:52,000 --> 00:02:59,000
So over here, I got the output of this expression according to the variable X.

36
00:02:59,000 --> 00:03:04,000
So this is how you can use node expression node in labview.

37
00:03:05,000 --> 00:03:05,000
Thank you.
