## simplify polynomials?...

Maple

hi all.

I have calculated an integral. the answer is a polynomial containing large power of  parameters ( i.g. x).

how could I reasonably simplify the polynomial? it has a long function too. ( 5 pages)

thanks.

## derive a function for goursat problem?...

Maple

hello.

I have calculated an integral equation (general goursat problem) with an iteration method. I want to know how could I use MAPLE to derive a function for.

I found the first 4 iteration for function f.

the exact problem is Uxy=2.U.Ux .

U(x,y)=2x on y=x^2+x and U(x,y)=3x^2 on y=0.

I want to find the U function.

y=t^2+t

U0=2t-3t^2+3x^2

Un=U0+int(2*Un*(Un)x)
