Sin, Cos, Tan

SRSDS — Wed, 24 Jan 2024 12:37:30 GMT

I am using a formula in a constraint parameter.

For some reason Sin(1) = 0.0175.

Cos and Tan give odd numbers as well.

Anyone understand what it is doing?

Bonjour @SRSDS

It is probably only from the "display" the real numbers are stored in floating point, no doubt.

I just put sin(1) into my calculator and it is giving me the same as AutoCAD (0.0175).

Previously I was putting it into Google and Excel and both were giving me the answer of 0.841.

Google and Excel are using radians as input and my calculator and AutoCAD are using degrees.

Bonjour @SRSDS

Be careful, however, if you use Autolisp, it always works in radians.
