trigonometric function parameter

[Tarkus]

it will be trivial but I can't do it:
how do I write in the parameters, the expression to have an angle according to the two lates of a triangle?
I would need the cotangent (?) but I can't find the right expression.
a tangent expression: tan(l2 / l1 * 1 gr) takes it but the cotangent as I write it?

 

[Matteo Cappelli dis.CAD]

with the tangent there is:
tan(expression)
atan(expression)
tanh(expression)
atanh(expression)

but if you go to the help link, you will have other exampleshttp://help.autodesk.com/view/invntor/2016/ita/?guid=guid-0106478a-b340-4164-a81b-866062877d60

Yes, I've seen it before, but by writing those suffixes, I'm mistaken,
For now it makes a fair and usable value by obviously giving the grades and the expression:
tan(module/diameter_primitive_vite_lifting).
However the equation remains written in red with warning:
Unmatched unit specifications.
and I can't understand where I'm wrong

Sorry, I put the specific parameter description for my job.
I wanted to write tan(l2 / l1).

I'm afraid to say a cabbage and I don't have time to check, but:

if cotangent is = to tangent^-1 should be equal to 1/thickness
so if you write 1/(tan(l2/l1)) it could come.. .

I tried anyway, and it doesn't work, but I found the way:

write: atan(l2/l1) , but in the line of that parameter make sure you have put it as "unit/type" gr and that the two values of l2 and l are in metric units (mm for example)

I tried and worked, I'm sure I had already tried and didn't work, maybe I had made confusion between gr and up.
or perhaps he needed a day of reflection :wink:.
thanks ilario :biggrin:
