Well... basically its a guide to curve sketching using a step by step guide, (its border line slide showish, but plz cut me some slack, I'm new at this) its not perfect, its not the prettiest thing, but she gets the job done.
So much white space
The need to lengthen the pauses for longer bits of text at the start is obvious enough, but otherwise there's not much to hold interest in this, and little if any explanation of the steps other than naming them.
Clearly enough effort went into making it run smoothly, but the screen is a bit bland and empty even for a slideshow, so maybe the black parts could be made bigger.
You might want to add a button to go back a step as well.
Not enough steps
This was a pretty good tutorial, but it skips a lot of "in-between" steps needed to solve it. Also, I'm pretty sure the math was incorrect for finding the domain... It's been a while since I've done this but I thought it was supposed to be (-8), not 8. Anyway, not a bad flash, but you just need to show more steps.
I likes
Not too bad at all. You might need to slow the intro text down a bit, I'm a fast reader and I didn't manage to read it all ^^; I know it's only the intro anyway though. Also, I don't know how simplified you intended this to be, but if it was meant for a someone who was new to this, you need to explain the terms more - personally I don't do this math, so I don't understand it at all.
Aside from that, it is good.
