 **************************************************************
 Calculate polynomial approximation on each step of interval 
 
 How to use: 
	Place LINES_POL.DLL in the program FindGraph subfolder "Appr".
	Start FundGraph.
	Start The Wizard of approximation.
	On step 2 select 'User defined function'.
	If all right, on step 3 your function will appear in list.

 Approximation function:
	Lines  on Step: y(i) =Ai0 + Ai1*x...+AiN*x^N)

 Parameters:
	Step = 
	N = pow of polynomial approximation in limits from 0 to +5
 
 Example: 
        Interval x: 0 - 10
        Step = 2 
	N=3
	V(U, i) = Ai0 + Ai1*U + Ai2*U^2 + Ai3*U^3
        i = 1,2,3,4,5
        4x5 = 20 coefficients
