Now this program will solve the Arc Length of a circle, that is if you know the radius/diameter and the central angle or C.A.

wow nice. thanks for this!!

 

Yep even getting one person to use a program is always worth making it.

 

Damn man thank you so much haha.

 

Ummmm, if you can't do this math you should be in first grade... D:

 

Yea, have fun using the program on a test We'll see who passes then.

 

You can't use a program in the middle of an exam?
But good program anyway

 

This is probably the most basic math I have ever seen (other than simple addition and subtraction). Okay, that was exaggerated, but you get my point.

Pythagoras' Theorum definitely isn't hard. Right now in my Year 9 class I am bored because everyone is struggling with Trigonometry, and I can complete the entire page of questions in a few minutes. Thank goodness I am elligable for Mathematics C next year, finally something that suits my level.

It is decent for what it is, however you don't need a program to do such things. A scientific calculator program would be infinitely more useful.

 

its that hard to write h^2 = a^2 + b^2?

 

or c^2 - b^2 = a^2

D:

 

Loll wdf

 

Oh, I quite like being challenged. If I didn't I'd be getting low grades like the rest of my class. ^_^

 

LOL, I am taking math online instead of through my school now, or I hope I am so I can fly through the info, so I am not bored.... And so i will have taken calc before 11th grade...

I was bored as shit last year and got an A- at the end of geometer, cuz i got 100s on every test and quiz, except the first one, but i never did homework... in math let me be challanged!!!

 

Thanks for this, should prove quite helpful =D

 

noice lol

 

Good for educational purposes anyway, and did you make this yourself?

 

I would bet he did... Its not that hard... and if you can not do this easily you realy need to go back a few years in math. :/

 

Very nice and very useful .

if no one wants to compile it etc, i made a jar for you :O

whats the point of going to a class if you are just going to cheat. Kind of a waste of time.
