Degree can be defined only if the equation is a polynomial in:
AConstants
BLogarithms
CFractions
DDerivatives
Answer & Solution
Correct answer: D. Derivatives
1. The degree counts a power of a derivative.
2. That count makes sense only in a polynomial in the derivatives.
3. So the equation must be a polynomial equation in derivatives.
