Just a bit more Calculus, Because why not.
Posted on Friday, March 28th, 2014 at 9:37 pmSo 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.

I’ve ordered the study guide for the Strand book. It is being sent here. I’m going to give it try. Of course, I also ordered a small book about building canoes from fiberglass. In other words, I will be distracted. What does my favorites psychologist say about my habits of “avoidance”?
Please remember that you’re the first person who hears what you say. Everything you say can be called “self-talk.” So, when you send me a post that says “I just don’t get it” I hear you say “I just don’t get it” and – as a guy who loves you – I hear you “un-teaching” yourself, I hear you setting an artificial standard, I hear you telling yourself something nobody should be telling you. I say You are as Good and as Fast as You are supposed to be. I say You are doing something no one I know is doing – taking Calculus for Fun.
Come to think of you it – You may NEED a psychologist! Calculus for Fun?
Oh, and, of course, Profit. Hmm. You ARE very clever.
You’re getting paid by the word. So, you can say anything you want – silly, succinct, whatever.
Ellen: In the past couple of posts you talk about online resources you are using to solve problems in the course material. It would help me if you made links to those sources in you post. Do you know how to do that? D
