recently I saw a cartoon about it geometric solutions of billiard game. it was a cartoon where Donald Duck was taught about presentation of mathematics in the life and he was given some geometric ways to play the game, e.g. directions to beat the ball and its formulas...

You're refering to "Donald Duck in Mathmagic Land", and as for the equations, I dunno.  But if you imagine hitting a ball straight on (with no english...no spin), then the natural angle (after hitting a second ball) will carry the ball off the tangent at the point the two balls made contact, while the second ball will travel at a right angle from the tangent.  In other words, picture in your mind you just just shot the cue ball at the 9 ball.  Got it in your head?  Now slow it down to the point where the two balls make contact and pause.  Now, if you don't know anything about tangent lines, I've got some info below.  Basically, a tangent line touches a circle (like the balls) in ONLY one point.  When the two balls hit, the first ball will travel along the tangent, while the second ball will always travel at a right angle.  Again, this is WITHOUT any spin, which will either increase or decrease the angle of the path of the balls.  That's one way you can control the balls and use them to your advantage, but you can start with learning the natural angles.  Practice...you'll get it.  Hope this helps :-P

I don't really know, but I wanted to tell you that this is my favorite all-time question on this site.\n\nI WISH I knew how to rudder-fy a duck--I'd really love to help you out with this one.\n\nI do have a question though--if the duck didn't swim in circles (or at least ovals) wouldn't the duck crash into the side of the tub?\n\nThanks for posting this this morning.

What is the point in being a God if you cant draw circular triangles. What kind of a God z dat. God can create rectangular s holes against the cylindirical     c ocks ....        if she likes...\n\n Like square pegs in round holes exactly    ...s,hit away...,\n\n get lost body\n\ndumbass \n\nGod damn you\n\nYou arent a true atheist\nWhat is going on here I really cant understand  Am I a believer? Where is my wine bottle then?

did you ever play that game when you were a kid - you all sit in a circle and someone whispers a message into the next person's ear, it travels around the whole circle in whispers until the last person speaks it aloud? Remember having a laugh at the crazy hogwash that it tended to turn into by the end of the round? Now imagine that it is not a bunch of kids having fun for 10 minutes, but a large number of powerful people with varying agendas who played this little game for 2000 years...;-)

Oh man I remember this...but wasnt it a cartoon...lets see.\nYou might want to check out http://www.sitcomsonline.com/ I vaguely remember what you were talking about but you may find it there...

Properties of mathematics makes it work. I'm not sure exactly what it has you do but essentially it does this.\n\nIf your number is X. You add 5 to it then subtract 5 from it and you get your original number. Of course the nice ones hide the fact that your doing exactly this. \n\nDavid Copperfield did a TV bit once where he had a 3X3 square. You start out at any square you want and move according to his directions. After each move he took away a square. In the end you always end up on one square. That was cool. Anyone heard of it?

Has anyone ever seen that comic strip that had the kid walking down a hallway with a HUGE sign that said "I'm missing out on an important educational opportunity because I have to tinkle"? My teacher did that, and made it a lanyard so we had to wear it around our necks. I hated that so much...\n\n~~Naomi

Here is one example...the bouncing ball. Just google that in and you get a bunch of results.

Very good to see that you sincerely want to develop interest in it and have better knowledge.  Geometry at your level fortunately is very visual (since it is mostly 2-d).  The following link has all the Euclid's Elements along with some cool interactive software.  You only need to go through a small part of it..Just play with the software (drag red dots around etc) and develop a feel for geometry first. At first, skip all proofs; just try to understand the statements (postulates, propositions, etc).  That might get you hooked on geometry.  Once you get a good feel for geometry, mensuration falls into place easily.\n\nhttp://aleph0.clarku.edu/~djoyce/java/elements/elements.html\n\nAlso play with some simple ideas: always think of a parallelogram as two triangles joined. Likewise, any polygon as a bunch of triangles.  Visualize a complex object in terms of simpler, more familiar "building blocks".  \n\nPlay string 'games': take a piece of string,  tie the ends together to form a loop.  Lay it flat on a table.  You can take a few match sticks and push out the string with the sticks tight so that the string looks like a straight line between any two sticks. You can make any number of polygons (triangles with 3 sticks, rectangles, squares, trapezoids, etc 4 sticks and so on, all having the same perimeter. Think of maximizing the area inside the string with 3 sticks: what do you notice about the angles, lengths of sides? How about with 4 sticks? And so on. \n\nRemember, develop visual intuition first. But pictures are not proof! So, you have develop the ability to make precise argumens using axioms and previously proved statements as well.  But that can come later.  Understanding and discovering facts is much more important than proofs (do not take this as advice to skip proofs, though). \n\nOne more thing: after having read a proof, sometimes you feel that you followed every step, but yet you don't "get it".  If that is the case, you have not really understood it.  You have to get to a point where a proof is not ten impossible-to-memorize steps each of which you understand.  And with practice, you can!  Think of biking: A robot may need to 'perform many steps' such as holding the bike, lifting the left foot, resting on a pedal...  Perhaps we learn the first time like that; but at some point it becomes so natural that we stop thinking about the individual steps and concentrate on higher goals.  Same thing with math.\n\nYou learn math primarily by doing. Good teachers, books, and software provide an immense boost in the process -- but they are all secondary to your own involvement.\n\nHope that helps and stay with it!

I CRACKED MY HEAD OPEN LAST NIGHT TRYING TO SOLVE THIS ..... PUZZLE. THAT CRAZY 15 JUST WON'T BUDGE. I JUST COULDN'T FIND A WAY TO GET HIM IN THE RIGHT SPOT. \nsorry. and i did it on paper, too. try that for a change (desperate). i really like puzzles, but this one..... drove me crazy :((((((

What the kids ask me for (I'm an art teacher)...usually SPONGE BOB (UGH), TWEETY BIRD, DORA, ETC....unfortunately that is NOT the type of art I enjoy creating!!!!

I tried as well... and these are a few websites I came up with. The second actually creates flashcards in PDF for viewing and printing. But these are the old standard flash cards for mathematics.\nNow... this last link is for some pics of classroom posters "Classroom Rules" and there seems to be many to choose from.\nI hope this helped... drop me a line if you need more help, I work at home and usually listening for chat windows to open.\nGood Luck to you,\nur2goofy
