So the "junk" eventually approaches some number which is multiplied by \Delta x^{2} and since \Delta x goes to 0, the "junk" eventually disappears?

I've started listening to the lectures for the MIT OpenCourseWare 18.01 Single Variable Calculus class. I understood all of it up until the teacher found the derivative of xn. Here's what he wrote on the board: \frac{d}{dx} x^{n} = \frac{\Delta f}{\Delta x} = \frac{(x+\Delta x)^{n} -...

Thank you so much! As for math...I haven't gotten to calculus yet, so it's probably better for me to stick with the second book (Cutnell and Johnson) for now. However, do you know any good books for learning calc, or should I post that in the math section?

I was wondering if there were any good books or courses out there that I could use to learn physics. I'm completed a basic high school level course in physics, but that's all. Are there any good teach-yourself books out there? I'm mainly interested in quantum / particle physics, but I know...
