Hi;

I can solve for your example. I am getting,

and there is a good method.

No problem, the problem is with me, I am trying to get us lined up correctly so that we are working on the same thing.

Very likely, Mathematica or any CAS will be able to help you. I will see if I can come up with a method that gets your answer for this example you posted. Hopefully then, this method will be able to do others too.

I imagine the R(1) would be (AT). R(2) = ( (AT)-S)T and R(3) = (((AT)-S)T-S)T? Do I have it right?

Hi;

A couple of things first.

That thing you are calling a series looks like the Horner form of a polynomial.

T^n*A-S*(T^n-1)/(T-1)

That is not an equation. An equation has an equal sign.

The last line. Is this what you mean?

That is the integral of 2x. The c is called a constant of integration.

You mean this one

Can you post the link?

Hi Zeeshan 01;

When you ask a question please be more specific.

Well, what did you think of my post #21?

Okay, I see your corrections. Now the problem is solvable.

Hi Mathegocart;

Also, there has to be more constraints put on a and b. Are they integers? Positive integers?

He should leave out the f(x). It has no meaning here.

It should be

2) 15. Let f(a,b) be defined as a^2+b^2-2, which of the following CANNOT be the value of f(a,b)?

(a) 0

(b) 2

(c) 3

(d) 6

Is it 2?

What kind of numbers are a and b? Integers? What other constraints are put on them?
