Question about Trig functions in Paremeters

[cwilko]

Hello All

Lately it seems the only questions I have to ask is to do Parametric Trig equations.

So here we go again.

I am creating an equation driven part with a few Trig eqautions. (Not that difficult until now)

One equation I need to input requires the Trig function Cotangent (cot).

eg. cot (x deg / n ul) with the unit type set at (ul)

This syntax does not work.

But when I rewrite the equation as 1 ul / tan (x deg / n ul) or tan (x deg / n ul)^-1 ul I get the result that cot should give me.

Does Inventor not support the Cotangent, Secant or Cosecant functions?

Or am I just misrepresenting the syntax description?

no cot, so guess you're stuck with 1/tan
