The number of arbitrary constants in the general solution of a differential equation of fourth order is:
The number of arbitrary constants in the general solution of a differential equation of fourth order is:
- A. 0
- B. 2
- C. 3
- D. 4
Answer: D) 4
Explanation: The general solution of an nth-order differential equation contains exactly n independent arbitrary constants. Thus, for a 4th-order DE, there are 4 constants.
