Category: Differential Equations, Integral Calculus

"Published in Newark, California, USA"

Find the general solution for


Solution:

Consider the given equation above


The given equation is a 2nd Order Differential Equation because the second derivative of y with respect to x is involved. We can rewrite given equation as follows



Multiply both sides of the equation by dx, we have 




Integrate on both sides of the equation, we have 




Multiply both sides of the equation by dx, we have 


Multiply both sides of the equation by dx, we have 




Integrate on both sides of the equation, we have 



Consider


If 


then


If 


then


Hence, by integration by parts




Substitute the above equation to the original equation, we have






where
