For avoiding confusion, the coefficient that is not attached to unknown functions and their derivative is generally called the constant term rather the constant coefficient. In the context of differential equations, an equation can often be written as equating to zero a polynomial in the unknown functions and their derivatives. This will depend on the domain restriction and on the relationship with other variables. What is a coefficient, term of an expression 5x+8y? [1][bettersourceneeded] When the coefficients are themselves variables, they may also be called parameters.
