Lecture 1

All right! Computer science skillz, here we come!

If you haven't already, take a look over at this page and make sure you have the correct version of Python installed on your computer. Remember, if you install 3.0 the code you write in this course will not be compatible.

Lecture 1 video is here, and covers definitions and other introductory things. In an ideal world, I would have watched it already, but it's currently playing in another window while I multi-task, and I didn't want to wait any longer to put this post up. It seems basic thus far, but I shall edit this post if I come up with any questions. Also, feel free to comment with anything that doesn't make sense to you. We have over 25 people following along and we're all beginners, so we should be helping each other out. :)

Edit 1:

Ok, I've watched the lecture, and aside from not being able to see what he's typing on the computer screen, I'm feeling pretty good. I'm going to take some time over the next few days to dig into the readings and see if I can't get an idea of what was on the screen.

Bit tardy to this. One thing I didn't get was "recall" exercise on the IDLE getting started...I just don't know what it means, not come across that in math terms.

This threw me off too. I thought it was a math term as well. But they were just giving a reminder for the quadratic equation to use to answer the problem.

Formula:
a*x^2 + b*x + c
x1 = ( - b + sqrt ( b*b - 4*a*c ) ) / ( 2*a)

Use this formula to solve the problem to find the positive root of the following equation:
34*x^2 + 68*x - 510

a=34
b=68
c=-510

solve for x
x1 = (-68 + sqrt (68*68 - 4*32*-510))/(2*32) (this will give you the value of x) which you put in place of x in the problem above.

I think I did this right - it's been a while.

Furearlz? That's marvelously good to know.
