well, that how the question is written on the sample test. midpoint http://www.youtube.com/watch?v=fKtSR0_xf5g"

I have, but I don't understand your question. There is nothing else to show, there is no math involve on the other two steps. You or someone that knows what they are doing, should be able to answer question 1 and 3 by looking at the data. You want more work 2)...

there is nothing else to show

I am solving a sample test for my test on monday, this is the question: Table(1) have results from applying the midpoint and trapezoidal rule on 2, 4 and 8 panels npanels...midpoint...trapezoid 2...2.19998820...2.48452890 4...2.26805993...2.33225855 8...2.28422520...2.30015924 1) do...

Homework Statement The Gaussian Elimination with Partial Pivoting algorithm when applied to the following matrix A[-3 0 4; 5 2 -6; 0 0 1] Will construct matrices P, L, and U 1- What are the defining properties of the matrices P, L and U? 2- What relation do P, L, U and A always satisfy...

Is this one f(x)= 6x^2+Y-6

the values in which the interpolation will take place?

:smile: I solve for a, b, c using the solver I got 6, 1, -6 So I guess the quadratic polynomial that interpolates the data is f(x)= 6x^2+Y-6, correct? In this part, is he asking for the 3X3 matrix of the 3 equations? a=[1 -1 1; 1 1 1; 2 2 1] b=[-1 1 8] where a*X=b

Like I said I don't remember anything my brain is fried for some reason. Looking at the data I just know that they are points (-1,-1) (1,1) (2,8) I got -1=a-b+c 1=a+b+c 8=4a+2b+c ?

Homework Statement Given the three x-values {-1,1,2} and the corresponding y-values {-1,1,8}, write down the three equations that define the quadratic polynomial that interpolates this data. I have completely forgot how to do this. Thanks Homework Equations IDK y=mx+b...

no! I was given this in part 1: which I solve, and is on my first post. On the second part I am suppose to do this:

Homework Statement For part 1 I solve the problem and I got the follow equation and results: .25x+.10y+.05z=1.15 x+y+z=9 -2y+z=0 The solution is x=3, y=2, z=4 Now I have to solve this by hand with the equation in matrix form using elimination matrix Homework Equations EAx = Eb The...
