How do you solve a linear differential equation using an integrating factor?

Click For Summary
SUMMARY

The discussion focuses on solving linear differential equations using integrating factors, specifically addressing the transition from the first step to the second step in the solution process. The key point is that after applying the integrating factor, which in this case is e^(x^3), the next step involves differentiating the product y(e^(x^3)) to retrieve the left-hand side of the initial equation. This requires an understanding of the product rule of differentiation to effectively reverse the operation.

PREREQUISITES

After multiplying the given differential equation by its integrating factor we get the first step,but I simply couldnot understand the second stage,pls explain it to me.

Notice in the second step, if you differentiate y(e^x^3); you will get the left hand side of the first step. so from the first step to the second, you have to undo the product rule of differentiation.
