Random math problem.

Post by keybounce »

So what is the integral from 0 to 6 of x^2-5 dx?

Working from dusty old math, that's 1/3rd x^3 - 5/2x^2, at the edges.

For 0, that's 0.
For 6, that's 1/3 * 36 * 6 - 5/2 * 36

That simplifies to 36 * 2 - 5 * 18

Or 72 - 90

Or -18

How can the answer be -18? It's been too long; what am I doing wrong on the integral?

Or instead of trying to do the math you could just brush up on your Hitchhiker's Guide! :wink:

What's the derivative of 5/2x^2? (Hint: It isn't 5.)

If there were more random higher math questions in Game!, I wouldn't have been bored away by now.
