Homogeneous differential equations

Click For Summary
SUMMARY

The equation 3y'''' + 21y'' + y' + 6y = 0 is classified as a homogeneous differential equation. The absence of a term with a non-zero coefficient for y''' does not disqualify it from being homogeneous; rather, it indicates that the coefficient is zero. The definition of a homogeneous differential equation pertains to the structure of the equation rather than the number of terms present. Understanding this classification is crucial for solving and analyzing differential equations effectively.

Is this a homogeneous DE?
3y'''' + 21y'' + y' + 6y = 0

So... since a(n-1)y''' is missing, would this still by definition be a homogeneous differential equation?

It's not "missing", it's just the coefficient of y''' is zero.
Check the definition of "homogeneous DE" - does it refer to the number of terms present?
Lastly: why does it matter what it's called?
