Hello,

I have try symbolic algebra computation with list,

in c language. (It is only for fun)

This is the result of the example : c13.c

/* ---------------------------------------- */

A_n :

[+][a * &cos(x)^(1/2)]

[+][a * x^(1/2) * &cos(x)^(1/4)]

[+][a * &cos(x)]

I factorize A_n = (B*A)

B :

[&cos(x)^(1/4) * a]

A :

[+][&cos(x)^(1/4)]

[+][x^(1/2)]

[+][&cos(x)^(3/4)]

I refind A_n = B*A

C_n :

[+][a * &cos(x)^(1/2)]

[+][x^(1/2) * a * &cos(x)^(1/4)]

[+][a * &cos(x)]

Press return to continue.

/* ---------------------------------------- */

This is the result of the example : c14.c

/* ---------------------------------------- */

A_7 :

[+][a * &cos(x)^(1/4) * &sin(x)^(1/4)]

[+][a * &cos(x)^(1/4) * &sin(x)^(1/4)]

[+][a * &cos(x)^(1/4) * &sin(x)^(1/4)]

[+][b * &cot(x)^(1/4) * &tan(x)^(1/4)]

[+][b * &cot(x)^(1/4) * &tan(x)^(1/4)]

[+][a * (x)^(1/4) * &ln(x)^(1/4)]

[+][a * &exp(x)^(1/4)]

I combine the same lists

A_4 :

[+][a * &cos(x)^(1/4) * &sin(x)^(1/4) * 3 ]

[+][b * &cot(x)^(1/4) * &tan(x)^(1/4) * 2 ]

[+][a * (x)^(1/4) * &ln(x)^(1/4)]

[+][a * &exp(x)^(1/4)]

/* ---------------------------------------- */

If you can give me the list of the biggest mistake.

You can try the code here:
