Re: Position of prime for derivatives

[Otared Kavian <otared@gmail.com>]

Hi Mikael,

You are correct, the position of \prime depends on whether there is a next character or not after it, and it seems that this has an effect on its position for characters having a subscript as in
	$f_{1}''(x) \neq f''_{1}(x)$ 
	$f'f''f'’'$
Best regards: OK
