''Oos-wes opening hiperbool:''
:<math>x = a\sec \theta + h\,</math>
:<math>y = b\tan \theta + k\,</math>
''Noord-suid opening hiperbool:''
:<math>x = a\tan \theta + h\,</math>
:<math>y = b\sec \theta + k\,</math>
In beide formules is (''h'',''k'') die middelpunt van die hiperbool, ''a'' is die semi-hoofas, en b is die semi-kortas.
