# Python | Numpy np.lagdiv() method

`np.lagdiv()` method is used to divide one Laguerre series to another.It returns the quotient-with-remainder of two Laguerre series `c1 / c2. `

Syntax : `np.lagdiv(c1, c2)`
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high.

Return : [ndarray] Laguerre series coefficients representing the quotient and remainder.
