The order of a differential equation is the order of its:
ALeading variable
BHighest derivative
CLowest derivative
DLargest constant
Answer & Solution
Correct answer: B. Highest derivative
1. Several derivatives may appear in the same equation.
2. The order looks at the one of highest order among them.
3. So the order is that of the highest order derivative.
