Determine the order and degree of d3y/dx3+≤ft(dy/dx )4+y=0.
- Order 3, degree 4
- Order 3, degree 1
- Order 1, degree 4
- Order 4, degree 3
Answer
B. Order 3, degree 1
Solution
The highest derivative is d3y/dx3 (order 3) and it appears to the first power (degree 1). The power 4 belongs to a lower derivative.
