# SeriesCoefficient

SeriesCoefficient[series,n]

finds the coefficient of the n -order term in a power series in the form generated by Series.

SeriesCoefficient[f,{x,x0,n}]

finds the coefficient of in the expansion of f about the point .

SeriesCoefficient[f,{x,x0,nx},{y,y0,ny},]

finds a coefficient in a multivariate series.

# Details and Options

• In the form SeriesCoefficient[f,{x,x0,n}], the order n can be symbolic.
• The following options can be given:
•  Assumptions \$Assumptions assumptions to make about parameters Method Automatic method to use
• For explicit SeriesData objects, the form SeriesCoefficient[series,{nx,ny,}] can also be used.
