ASIN ACOS ATAN

[bruno_cadet]

Hi there,

All functions works well in dialog box except Inverse trigonometry functions asin, acos and atan !

Is there a solution ?

Thanks

Seems to work for me, have you set the units correctly?

Thanks.

I've found the solution just after posting...

Sometimes the brain blocks !

atan() saved my work...

Thanks Hugues.

Okay it works for constants but what about variables? ( User parameters)

[jhackney1972]

You have a unit conflict.  You are multiplying your MainSeatAngleDiv expression by 1mm, it needs to be divided by 1mm instead.

Here is my Parameter Table with the correction.

Ohh I must've missed that operator in the docs somewhere, thanks. Why are we dividing by 1 ?

Thank you for your help, however for me the problem remains:

[jhackney1972]

You have an error in the placement of your parentheses.  I noted this with the red arrow.  I attached a corrected Parameter table to shown it works if enter correctly.

The answer to your previous question, divide by 1mm, is to change the parameter units from millimeters to no units.  In a basic division millimeters, in the numerator, divide by 1mm will cancel out returning a value with no units.
