VI Farenheit and Celsius set up HELP

[sguy12]

1. esign a VI to convert temperature from Degree Fahrenheit (F) to Degree Celsius (C). The VI accepts Fahrenheit from the user and displays the corresponding Celsius. Use the following equation:
   
   F = (9/5)*C + 32
2. Design a VI that computes f = 5x² + 9y – z, where x, y, and z are real numbers. Provide two solution methods. For the first solution use only arithmetic functions (such as Square, Add, Multiply, and Subtract). For the second solution use the Formula Express VI. Which solution is easier to program? Which solution provides a quicker way to change formula? Which solution executes faster?

Seems like simple homework problems.

I'm sure you learned enough in class to be able to  finish it yourself.

Good luck and earn that "A"!

Hmm... guess it depends if I can guess right with the formula node or need to open the detailed help to get the right syntax...

I'd be tempted to disagree with what I expect is the desired answer based on the nice quick-drop plugins...

I would rather use the Formula Node.  I often find it easier to read and edit when dealing with some complex math.

I don't use the formula node because I really suck at typing.  A mouse-driven programming language was a gift from [insert the mailing address of your favorite deity/deities here].

I typically don't use the Formula Node because I don't normally have to deal with weird/complex math.  But occasionally (once every few years), I do and it is nice to have the Formula Node around for those situations.

At my previous company, I had to  re-invent the wheel because they only had LV basic 😞
Implementing a linear regression line fit in native LabVIEW functions started to get ugly...

Formula node could of made it a bit nicer... but that is cheating. LOL

You could have made it a lot cleaner by implementing a Square function and used the compound node for the three factor multiplication (or made a sub-vi of it, or just change the order of the wires since multiplication is commutative.

The simplest solution is to use physical quantities.  You won't need to use any functions at all.

I always love how someone who creates a post trying to trick people into doing their homework for them, never responds back, but there is a long thread among the regular forum users anyway.
