In algebra , a septic equation is an equation of the form
where a ≠ 0 .
A septic function is a function of the form
where a ≠ 0 . In other words, it is a polynomial of degree seven. If a = 0 , then f is a sextic function ( b ≠ 0 ), quintic function ( b = 0, c ≠ 0 ), etc.
The equation may be obtained from the functi... | https://en.wikipedia.org/wiki/Septic_equation |
