Mr m:

You're half right I can't get that answer but Eric did it in less than 5 min. He said to tell you that as long as he is around you're second best. smile Can you make it to Canaveral this weekend?

Eric said he got it 2 minutes faster than you did. smile He said that you'll put it in the brittle thread.

That's right. How did you get it?

A person picks from the set of numbers {1,2,3,...100} eighty of them without replacement that sum to 3690. In how many ways can they do that?

Merry Christmas to everyone! smile

Did it change your mind about formalism?

I finished the video too. Did you see SW close to the end? What did you make of that? smile

When you're trying to do numerics you should check your work. You're not doing that. Please plug in those answers to check.

You do eat tuna don't you?

There has been much discussion about that particular point. I do not believe it is posted anywhere in the rules clearly. I would suggest not giving the full answer away but rather try to get the OP do it for himself. Help him along with hints and suggestions or show him a bit of math that can get the answer.

Is that an answer?

#12 Re: Help Me ! » surds » 2016-10-18 06:07:41


Since everyone else just gives the answer. I'll try it.

Hello thickhead:

Too much notation for such a simple problem don't ya think? I thought there was a rule against just giving away the answer like that? sad

Give a guy a couple of fish and he's bloated for a day. Teach him how to fish and he can open a good seafood restaurant that bobbym can eat at. smile

How about too easy. That will take care of tary-try-tree-tri-trey. smile

How do you say it, yall gots to come up with something a bit harder aye bumpkin.

#17 Re: Exercises » Bitter areas. » 2016-10-09 21:07:39


Quite elementary. smile

Have you tested that?
Does it get all the solutions?

You are doing what he did. You know the answer before you asked the questions.

The first thing I ever taught you was to never ask a question you didn't already have the answer to. - The Verdict

The verification you showed me 2 hours ago:

Yes smile

That is not factual.

I didn't say that the right answer wasn't posted. I said the correct solution hadn't been posted yet.

The solution you propose is longer and requires more work.

This solution uses the defining properties of both  ellipse and hyperbola. smile This is shorter.

It can be shortened more because you don't even need to know

. He could've got that with EM. It is obvious that solving 2 linear equations is terse and therefore best.

Next time just email me before you attempt to solve a problem that is a bit too tough for ya. I'll be glad to assist an old guy. smile
