POLY Function

POLY(t, a, b, c, d, ...)

Returns the polynomial calculation of the equation a + bt + ct2 + dt3..., with up to 8 coefficients (up to 7th order).

Parameters

t (REAL)

The polynomial variable.

a, etc.(REAL)

The polynomial coefficients, where a is the zero-order coefficient, b is the first order coefficient, c is the third-order coefficient, etc.

Return Value

Returns a REAL.

Remarks

This function supports between 2 and 8 coefficients (3 and 9 total parameters). This function is more efficient than entering the polynomial directly.

Examples

POLY(1, 1, 2, 4, 1) is the equivalent of 1 + 2t + 4t2 + t3, where t is 1.0 and returns 8.0.

POLY(0.5, -10, 5, -0.1) is the equivalent of -10 + 5t - 0.1t2, where t is 0.5 and returns -7.525.
