Graphing derivative of a function + tangent line on same graph. 70% done, I need help :(

[antek]

Hello Everyone !
I am using Labview 8.6 but the file is saved as labview 8.5. 

I am almost done with this assignment but i cant figure out how to draw a tangent line on top of the graph with derivative of the function.

Can someone please help me ? 

Thank you

No one knows ? 😕

Hi antek,

what are you looking for? Do you ask for mathematical background to your homework?

I cleaned up your VI a little bit...

[antek]

Thank you i will take a look at it.

What i am trying to do is graph tangent line on the derivative graph.  I am also not sure how to implement tangent line equation into my VI.

I cant open the file because its 8.6, could you save it as 8.5 ? Thank you. Sorry for double post

Hi antek,

well, you wrote: "I am using Labview 8.6..."

But here it is attached in LV8.5...

[antek]

Sorry for the confusion. I meant to say that i am using 8.6 in school and 8.5 at home.

Anyways, the simplified VI you did is not going to work for me since i need to be able to input formula.

Hi antek,

"since i need to be able to input formula"

Why do you need to? You have a precise duty with only one given formula - so you can "hardcode" it using LV functions. No need for formula node...

[antek]

I guess you are right, but i still wanted that formula node so i can test different functions.

Anyways how do i get the tangent line and most importantly how do i display it on one graph with the derivative of the function ?

Thank you !
