# Coefficient

 Coefficientgives the coefficient of form in the polynomial expr. Coefficientgives the coefficient of in expr.
• Coefficient picks only terms that contain the particular form specified. is not considered part of .
• form can be a product of powers.
• Coefficient picks out terms that are not proportional to form.
• Coefficient works whether or not expr is explicitly given in expanded form.
