Cotangent in Equation driven parameters.

[Trigg3r]

Hi all, I need a little help. I need to drive a diameter via an equation driven parameter but I need to use something along the lines of

' blah * (blah + cot(blah / blah)) '

which I've used before in SW.

I'm no maths genius but the only available functions are sin, cos, tan, asin, acos, atan and sinh, cosh and tanh.

Am I missing something or is it obvius and I'm just to daft to work it out ?  🙂

Hope that makes sense.

Cheers !

Hi @Trigg3r,

If I remember trig identities correctly (and it's been a while so I wouldn't be surprised if I don't) that cot=1/(tan(x)). Therefore for your expression:

' blah * (blah + cot(blah / blah)) ' should equal

' blah * (blah + 1/tan(blah / blah)) '

For reference, I used this link.

Thanks,

Easy when you know how eh ! 😄
