Ace asks. You answer out loud. Miss one and Ace explains it.

Pick a class and tap the chip. Ace reads each question in its own voice, listens to your answer, grades it like a senior engineer would, and saves every miss to a review deck.

Ace asksFor a first order linear differential equation, why does multiplying by an integrating factor help you solve it?
YouI'm not sure.
Here's the answer.The integrating factor turns the entire left side into the derivative of a product, so you can integrate both sides. This uses the product rule and the first order linear differential equation method in the NCEES Reference Handbook. Remember: make a product derivative, then integrate.
