* Mathematical operators are in roman. Usually this happens automatically. For example <math> \sin\alpha </math> (<nowiki><math> \sin\alpha </math></nowiki>). But some operators will require manually setting. For example <math> \frac{ \mathrm{d} x }{ \mathrm{d} t} </math> (<nowiki><math> \frac{ \mathrm{d} x }{ \mathrm{d} t} </math></nowiki>) and <math> \mathrm{arcsinh} </math> (<nowiki><math> \mathrm{arcsinh} </math></nowiki>). | * Mathematical operators are in roman.
