Question : 9
Total: 29
What is the degree of the following differential equation?
5x (
dy
dx
)
2
d2y
dx2
- 6y = log x
Solution:  
Given differential equation is 5x (
dy
dx
)
2
d2y
dx2
- 6y = log x
In the above equation the highest order derivate is
d2y
dx2
and its power is 1.
Thus, the degree of differential equation 5x (
dy
dx
)
2
d2y
dx2
- 6y = log x is 1
