Thanks!Your points are clear and easy to understand. Now I grasp the idea that dx is just a symbol but is also crucial in some equations. But I don't believe it makes sense to multiply dx by (-3) in this equation in my example. Can you explain that?

Thanks for correcting that error! But in antidifferentiation, does dx also mean delta x?

Thanks for your answer! If dx is just a symbol telling us which variable this is to be integrated with respect to, what does (-3*dx) actually means?

Hi, This is an example in "Barron AP calculus" I learned from some past threads that "dx" in integration either means △x which is a infinite number or indicates the variable with respect to which you're integrating. In the equation above, it seems that dx is multiplied by (1-3x)^2. Isn't dx...

Hi, My name is Kelly. I am a high school student in my senior year. I am learning calculusAB&BC for AP exam this May. Hope to meet you in later discussions.
