## simplifying with maple...

Maple

please help me here. I want to simplify the expression:

(-f(xn)^2*f(zn)+f(xn)^2*(D(f))(zn)*zn+f(xn)*f(zn)^2-2*f(xn)*f(zn)*(D(f))(zn)*zn+(D(f))(zn)*xn*f(zn)^2)/((D(f))(zn)*(f(zn)^2+f(xn)^2-2*f(xn)*f(zn)))

I just compied it directly from maple

## a least square problem...

Maple

please help me here:

I want to find the coefficients a, b , c of the following quadratic polynomial:

P(x) = a*x^2+b*c+c

I know the following:

1. P(x0) = d

2. Derivative(P(x0)) = e

3. P(x1) = f

4. Derivative(P(x1)) = g

Thansk in advance.

## finding coefficient of equation and solv...

Maple

Hi,

please help me here:

I have a polynomial:

P := x->a*x^3 + b*x^2+c*x+d:

Now, first i want to find a, b, c and d. I know the following:-

1. value of P at x0 let it be e. 2. value of derivative of P at x0, let it be f. 3. value of P at x1, let it be g 4. value of derivative of P at x1, let it be h.

i used the following command:

solve({P(x0) = e, (D(P))(x0) = f, P(x1) = g, (D(P))(x1) = h}, {c, d, a, b})

but i am not getting any output****

now i want to solve P(x) = 0

## Division of two Power Series...

Maple

Please help!.

How to do the following with Maple:

1. Create two power series:

p1 = e + c1 e^2 + c2 e^3 + c4 e^4+ ....

p2 = p1 + 1

2. Find division of power series

p1/p2
