The POLY(x,x0,a0,…,an) function returns the value of an nth order polynomial. You can define up to a 30th order polynomial.
Arguments
|
x
|
The independent variable. You can enter a valid expression for the independent variable such as 2*TIME.
|
|
x0
|
The constant offset of the independent variable.
|
|
a0,…,an
|
A set of polynomial coefficients.
