y"' + y2 + ey' = 0

Short/Brief Note
Sum
Advertisements

Solution

y"' + y2 + ey' = 0

The highest order derivative in the given equation is y''' and its power is 1.

Therefore, the given differential equation is of third order.

This equation cannot be expressed as a polynomial of derivative.

Thus, the degree is not defined.

i.e., Order = 3 and degree is not defined.
