Dear list,
how would you calculate with an expression this formula:
arctg(y/x)
the canonical object for this is [atan2].
since you asked about "expressions", use:
[expr atan($f2/$f1)]
looks like tan, sin, cos cannot be in the expression, does it mean I have to brake it into parts?
what do you see that i don't when creating [expr tan($f1); sin($f1); cos($f1)] ?
