Question

Which of the following statements is true regarding order and degree of differential equations?

Options

• Order can be a negative integer

• Order and degree, if defined, are always positive integers

• Order is determined by the exponent of the highest derivative

• Degree can be zero

Answer 1

Order is the order of the highest-order derivative present. Degree, when defined, is the highest power of that derivative. Order and degree, if defined, are positive integers.
