Canvas Experiment Thirteen

Looks almost like the finished product. The easing algorithm is the one thing left to do: Between one arbitarary position and another, "ease" the upper point to an angle between the point found with arcsin(), and the point found with ordinary radial arithmetic.

Blaise pointed me toward the Arcsin function, which simplified a whole metric ton of math. Haven't puzzled out the easing function yet, but now that I have the d→r function working fine, that's just a matter of aesthetics.

Awesome: Canvas Experiment 11. Now with no quadratic equations.

And Experiment 12. Moving at light speed today.

And here we go, thanks much to [livejournal.com profile] zanfur!

Experiment Seven.

For my next trick, I have to figure out where the blue line intersects the outer circle closest to where the orange line does, and draw just that segment. It's Just Algebra, with a little bit of algorithm.

Oh, might LJ Brain, help me with this mathematics problem: a man is a demolition derbyist. The probability of him suffering an injury during any one derby is 0.12.

I know that the probability of him suffering an injury in two derbies is ((0.12 + 0.12) - (0.12 * 0.12)). What's the (generalized) formula for him suffering an injury over n derbies?
