So I did a couple hours last this week just in the book. I was trying to see if I could do a couple extra problems based on what I had learned while doing problem set 1. It seems to be good practice, though I am still getting tripped up a lot. Got to look a bit closer at what I am learning I think. Maybe watch the videos a few more times? I do not know. Anyway, the fractions are what seem to cause the most problems. I think I know what I am doing when it comes to equations like ( x^2 + 2)^2. You have to take the derivative of the function as a whole, replacing the inner equation with the variable u. Then you have to take the derivative of the equation inside the parenthesis. Then you multiply them together, so you have an equation that is 2x2u = 2×2(x^2+2) and so on. The ones that stil trip me up involve fractions. I think I understand how to do the parts, the numerator and denominator, but the fraction that messes me up. The problems would be something like [ ( x^2 + 2)^2 ] / [ (x^3 + 3]. So what do I do with this? I guess I will have to find out. Probable more online digging. I should really make folders for all my online resources. That would make going back or making a review for the test a bit easier.
