Re: What do you think?

Must have. I getting to think I messed up pretty good here. Just trying to track it down. Thanks for the help, you were correct about going the other way!

Re: What do you think?

Anyway, did you solve the problem with that angle? What is the final answer you get? It may not deviate much...

Re: What do you think?

Hi gAr;

I tracked down the problem. I think it is a bug in the old version of geogebra. The newest one is getting your answer.

No, I have not gotten far enough along with answering the rest of the problem. Will post an answer as soon as I get there. Thank you for the help.

Oh, good that you found it out!
If any calculation is simple enough, I always double check with a calculator.

Hi gAr;

Your answer is correct. The ants are out of sight! Very good!

Re: What do you think?

Thanks for the help with the program that was driving me crazy! Glad you looked at the problem. How are you coming with the test scores problem?

Re: What do you think?

Good that you discovered the problem with old version, you can avoid the errors in future!

As for the test score's problem, I couldn't find a solution. Can you post the solution, if you are willing?!

Re: What do you think?

Yea, I wonder how many other errors it made? Anyway, at least I have something other than myself to blame for all those blunders.

Re: What do you think?

I was just kidding anyway. most likely, 8 thumbs over here probably was doing something wrong! The next step was to use the animation feature and have geogebra solve it.

Hi bobbym,

I don't know to use the animation feature of geogebra. Where can I learn it?

Re: What do you think?

Hi gAr;

There are tuts on the internet. One particular guy does a lot of them. Actually I have only scratched the surface with it but it has great power to solve problems.

I see them once in a while. But I never bookmark them. The next time I am looking at some I will be sure to post it for you.

Re: What do you think?

What do you think about this problem: We are required to find the speed(all different) of the ants such that they will not not be out of sight for a maximum time. Is it possible that they'll never be out of sight?

Re: What do you think?

For the last part I would say no, If there is some difference in their speeds it will get larger and larger until they are out of sight.

Re: What do you think?

New problem!

Find the center and the radius of a circle that passes through (3,7),(11,5) and (3,0).

A says)  Cannot be done, I told you math does not work.
B says)  It is not a hanger but it can be done.
C says) Yes, B has a colossal overestimation of what math can do.
D says) And he is usually wrong. I think the radius is 8.

Hi Howardroark and gAr;

Correct! Seems there are a lot methods to do those type problems.

The easiest is geogebra's circle through 3 points!

Powerful feature to be able to make high precision drawings and do experimental math with them.
