sine square function in formula node

Hello

 

I need to generate a function

I = Iz * sin^2(B)
where B = (pi/2)*(V/70)
Iz = 0, 0.1, 0.2, 0.3 ... 1.0
V = 1,2,3 ,4...135

 

I tried to do thi sin formula node. but cud not get it.

 

See attchment.

This will not work. B has 105 elements, and IZ has only 10. B and IZ must have the same numers of elements. And you should perhaps use a for loop not a formula node


Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Hey can you attach a vi that successfully implements the sine function in a formula node?  I need to make:

 

12 + 150sin(B(X-22000)) where B =  (Pi/7200).  Please help me out with this, and it has to be in a formula node to fit into my project.

 

Thanks for any help.

Why does it have to be in a formula node?

 

Is this homework?

Kind of - a class project.  Is there way to put a simple sine function inside of a formula node or not?  If not I need to do some major rewriting.
