Hey Thanks Alot! I just might pass on my unit test tomorrow because of you! :)

And screw the error, everyone makes mistakes! It's just a matter of if you learn from them or not :)

Thanks for the help!  The minor error was no big deal.

[jrendoso]

it is helpful, thank u.....

Yeah, he's trying to teach math, but can't do it himself. -1/8pi would be the answer good catch.

[Lutemann]

You're right. Out of 110 videos I made an obvious minor error. It must mean I can't do math. Are you sure you can think?

[ZzhydrocyfireX]

I agree with morrowchristine.

[morrowchristine]

in the final answer, wouldnt it be -1/8pi

because if you have -5=2pi(20)(dr/dt) and you divide both sides by 40pi, it would be (-5/40pi) which reduced to (-1/8pi)... rather than (-pi/8)

[Lutemann]

You are right! I'll do it over. Thanks.

[brettae89]

I'm pretty sure that (-1/8)pi is the same thing as (-pi/8)...uh yeah...

[morrowchristine]

Yes, (-1/8)pi is the same as (-pi/8)

but if you actually watched the video, you'd see i was correcting the NUMERATOR.

(-1/8pi) is NOT the same as (-1/8)pi

[Lutemann]

You are right. That's a typo. Thanks.
