I'm trying to thank people for their comments but it won't let me say the same thing over and over so excuse me if I say something really strange.
This a combination of math and art and can be used by people who know algebra and those who don't.
General Instructions:
Move the min/max (the highest or lowest the arch will go) up and down by dragging the button. Move the x- intercepts (where the arch will cross the x- axis) side to side by dragging the buttons. Click Graph to graph and Clear to clear.
Math Instructions:
This can help you find an equation if you known the x- intercepts and the min/ max. When you hit graph the equation will show up at the bottom. If the number is really small, scratch will round to 0, so if it says 0 is the coefficient to x squared, it is definitely invalid.
Scratch Instructions:
When you throw things up and out they generally fall in a parabola- like shape, so using parabolas in your projects will make them more realistic. This will help you find the equation to use, whether you know algebra or not. Move the x- int to where you want the object to start and land and move the min/max to the highest or lowest you want it to go. Hit graph and you the equation it gives (unless it says 0 x squared). The first number on the bottom is a, the second is b and the third is c. Use a repeat block and repeatedly change the x position by a fixed amount and setting y to ((a*(x position* x position))+(b*x position)+(c* x position)) and stamp then repeat. If that doesn't make any sense, feel free to ask lots of questions!
Art Intructions:
Whether you are familiar with graphing or not, you can make awesome art with the parabolator. Experiment with moving the slides slides, changing the color and background, stopping the arch part way and more. See if you can make pictures and cool designs!

this is amazing! must have taken a long time!
Thank you very much!
omg that is the best thing ever
Really? Well, thanks.
this could help me with cannon psychics
I'm glad! I'd like to see the project(s) you make!
(view all replies)totally awsome game. no wonder this was featured
Thank you very much.
cool!
Thank you. I am glad you like it.
i don't get it
Just move around the sliders and press graph. Change the colors. You don't have to pay any attention to the equation if it confuses you.
COOL XD <3
Thank you
please check out my new game update i would appreciate it :) (link to project)
cool, i might use it to make a game with launching gernades or something! thanks
Cool! I'd like to see your game if you make it.
I Made the scratch cat
check out my games. If I get five or more "Love Its" on my Friction Test 4, I'll make a sequel.
thats a lot of comments.

It's a good game, especially if you understand it.
Thank you very much.
Pretty awesome, once you get the idea.
Thanks Nory.
lol i love math O_O
I am glad.
(view all replies)u moof into trunt ond tull uts nut over
I think its kind of hard to figure out
Just move around the sliders and press graph.
(view all replies)That's amazing!
I have a new project in the series: (link to project)
sit yant
Thanks Chrischb!
Argh so complicated! Don't understand any of it, only expirementing with the colours. My head hurts!
Well, I'm glad you experimented. That's a good start! Sorry I made your head hurt...
Yay 652 and going;=>You may wish to move the coefficients so they come down and before X2, X
I tried that, but you never know how long the decimals will go and they sometimes run into the variables! I will see what I can do.
(view all replies)what version u use???
Shows what version it is.
(view all replies)1.3 is the first version that shows.
(view all replies)I made this with 1.2, but I use 1.4 now.
(view all replies)so this is the project that got it's picture in my iphoto! i've never seen it before, but it's on there somehow!
That weird!
(view all replies)im scared..... too complicated..... and too many notes.... my head hurts....
Sorry... I did get a little carried away.
Cool! check this awesome parabolator project (its not as good though) (link to project)
cool
Gracias
hehe.. wow that was a lil over the top!!!
omg i have no idea what to do!!!
Just move around the sliders and press graph. Change the colors. Experiment!
I made the things at the bottom say infinity!!!! I just set both the left and right sensors be set on the -172 and the up/down one to 190!!!
It works!
EPIC
I'm glad you think so.
OMG WITH A LITTLE OMG ON THE TOP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WHOA OMG OMMMMMG! copy+paste to 9 other videos then log under CP then go to the forest press F7 for membership AND INFINATE COINS! NOPE NO JOKE AND NO LIE! =D
he/she means club pinguin and dont spam.
huh?
nice :0 WHEW!!!!
Thanks!!
i actually think its god, so there!!
check out my games. If I get five or more "Love Its" on my Friction Test 4, I'll make a sequel.
(view all replies)Thank you. (I think you mean good)
Also, it is impossible to create a parabola with one x-intercept — if both are set to the same value, the graph is of a straight line.
y=x^2 :)
(view all replies)Yeah... Sorry...
I noticed that "min/max" is treated as minimum when it is negative and maximum when it is positive, yet a parabola could have a minimum above 0 or a maximum below 0.
Yes, that would make the X-intercepts become imaginary numbers, which is impossible to do on scratch. The only way to graph that on a scratch program would be if you had an equation, but I doubt that many poeple here have taken that level of math yet.
Yes, but then it will have no x-intercepts.
(view all replies)i dont get it
Well, if you know algebra, you can use it as a tool. Otherwise, you can make cool art.
What don't you understand?
(view all replies)Nice, I guess I won't have to pay 100 dollars or more for a graphing calculator! :D xD
Ha Ha. Have you seen my similar trig project? (link to project)
cool....
Thanks...
i made hill
That's cool.
wow, this is good, and even better, i understand it! :D
I'm glad you understand it. :)
SKILL FULL,FULL SKILL
huh?
this is awsome
Gracias.
(link to project)
dont spam.
Congratulations. You may wish to give the link to the Graphing calculator Gallery for people who wish to see stuff similar to your grest work. (link to gallery)
OK, I will. Thanks for the suggestion.
wow!
lolwut
Hey, Hasn't this already been featured before? I think it has...
i am confused but very good job i think this is for 14 and up
(view all replies)No. This is the first time.
THIS IS AWESOME. AFTER A FEW TRIES YOU START TO GET THE HANG OF IT... AND CONGRATULATIONS ON GETTING FEATURED.
Thank you very much. Have you seen my similar trig project? (link to project)
wha-t
I absolutely love it! I love how you incorporated math into gaming. I'm going to show my math teacher this. Thank you for posting this wonderful project!
Wow! Thank you.
nice
Thank you.
(view all replies)Very good job!
Thank you dapontes!
Yay! Someone likes math like me!
Sweet project and btw random question but how do do a (Link to project) i cant figure out how and congrats for featured!!
Yep! It works. You can do that with galleries and forum topics too.
(view all replies)Yeah... Like on your "stuff" page.
(view all replies)Thank you. If you are on a PC, right click on a link to your project. If you are on a Mac, control click. Then click on "Copy link location." Right or control click on where you want the link to be and click paste. In comments, it will show up at first as just url but when you come back to the page it will have the (link to project.) Hope that helps!
(view all replies)Congratulations! Featured!
Thanks you! I am adding this sentence so it doesn't say "Sorry, you have posted a very similar message recently."
(view all replies)very very very good project!! Congratulations!!!!!!!!!1
Thank you so much!
(view all replies)Please add this to my gallery!!!!! Plz Plz cool game PLEASE
Thanks! What's your gallery? You can add it there if you want.
(view all replies)Featured! Congrats :)
Thanks so much. My first project on the front page! I'm so excited. :)
so neat ! : )
Thanks
This is great! I love parabolas (one of my favorite curves) and this is a really cool way to let people play with them :)
Thanks! I love parabolas too.
I think this is a very fascinating project. I might even do a remix on this. Great work. Thanks.
Cool! Can you give me a link to your remix if you do it? I'd like to see it.
