Math program
« on: December 03, 2009, 01:57:02 pm »
I don't know if this post belongs here, but anyway, I am making a math program.
Anyone taking AP Calculus AB right now?
I am learning about Derivatives (which pretty much is what AP calculus is about)
So I wanted to program on TI 84 that if I input the function (even with trig functions) the program will give me the derivative.

I am very far into it. the program gives me the derivative as long as there's one function and doesn't have trig function in it.
But the problem is that I have no idea how im going to do with trig function.
Also, it is still buggy with the roots sign.

And it doesn't yet know how to combine like terms.

I will upload it as soon as I can~

Girls = Time * Money (Girls are a combination of time and money)
Time = Money (Time is money)
Girls = Money squared (So, girls are money squared)
Money = sqrt(Evil) (Money is also the root of all evil)
Girls = sqrt(Evil) squared (So, girls are the root of all evil squared)
Girls = Evil (Thus, girls are evil)

There already is such a program for the ti 84, does exactly what you are saying. its somewhere on ticalc,  i just haven't looked at the 84 section in a while. anyway, i am in AP Calc and derivatives with trig really arent that hard.
d/dx(sin(x))=cos(x)
d/dx(cos(x))=-sin(x)
d/dx(tan(x))=sec^(x)
d/dx(cot(x))=-csc^2(x)
d/dx(sec(x)=sec(x)*tan(x)
d/dx(csc(x))=-csc(x)*cot(x)
I take it you have already programed in product, quotient and chain rules? if not, id start with those before worrying about trig. it would also be cool if this program could do integrals. as for combining like terms? i have no idea.

ok, here is that 84 app.

Yeah, i wanted to program that in BASIC... and mine will show the steps in solving that.
Our teacher will destroy our grade with just one word: "HOW?" if we don't put the steps in.
I am trying to do the product and quotient, but don't know what chain is... haven't learned that yet

Hats off to you if you can make a program that will find antiderivatives.

Indeed, that is something that even modern day math programs can't do completely ^^,

i don't know what antiderivative is...
and i am learning chain rule today~

I am going to halt this thing for a while, and make it after i learn more about derivative

Math programs was what made me enter the community...


I should have released my math programs by now...

I was kidding :P

I kinda said that because I finished hi school several years ago and on Omnimaga, there are rarely any maths question since the entire forum is pretty much devoted to games

Math is originaly what got me into programing, since i didn't know how to use getKey for the longest time.  I once built a program to solve triangles, everybody wanted it :) But yeah, math programs are awesome!  After every math test i have at least 2 or 3 programs that i wrote during the test to help me out XD

and Wewt! 500th post!

ya math programs are very usefull because then you don't have to memorize the formulas you mearly have to remember what the program solves such as a sequence total(how much it adds up to) solver i created friday

I memorize almost all formulas because of the many times I use them.

What I found really cool is using lists in calculating stuff in statistics and sometimes probability with combinations.

The whole first year that I programed, I just programmed math programs.  I've only been programing games for about a year now.
I remember my great Slope program.  You had to put in any four of X1, Y1, X2, Y2, and M and it would give you the other one. :) Simple, but it sure was great. :)

That's why i asked if this post belongs here, since i knew that omnimaga is dedicated to calc games and music. And I had a lot of math programs to help, and my favorite one was solving the systems of equation with matrix, with steps showing.
