i am going to be crazy!!!where this error coming from????

Did you try running this in the Processing IDE? It would give you many other errors first.

For instance, 4eqation_Aequation_C does not make sense. Variables can not start with a number. You probably meant 4 * eqation_A * equation_C. I think there are a lot of * signs missing.

You also mispelled equation_A as eqation_A.

The problem is that you have declared equation_A and equation_B as arrays, but used them as floats, without the "[i]" part. You can not send an array of floats to sq().

In the rotte() function, you added an unnecessary float() when assigning x[i], as all the elements are already float.

It would be nice if, before posting your code in the forum, you formatted it in the processing IDE by pressing CTRL+T, and in the forum you surrounded it by <pre language="processing">yourcodehere</pre>. It would look so much nicer :)

such a simple error,thanks
