Interpolation Definition and 155 Threads

Could someone help me understand why interpolation rather than extrapolation should be used for calibration curves (with the exception of Standard additions). I know that extrapolation is less precise, but the book I've got doesn't over any more than that, and I think I need a little more detail...

If you have two standard 3d, orthogonal matrices representing axes of 3d coordinate systems of the same handedness, is it possible to find the vector about which you would rotate one of the matrices to get the other? If so, this would be a lot more intuitive than quaternions (at least for me)...

I have a 3-D traingle, and the edges are a,b,c. If I want to find a line interpolation at a point in the center, let's say that it's P(x,y)... My equations are \Delta Z = A + Bx + Cy \Delta Z_a = A + Bx_a + Cy_a \Delta Z_b = A + Bx_b + Cy_b \Delta Z_c = A + Bx_c + Cy_c In order to...

I was doing some last minute skimming through my book for my exam tomorrow and panic. Can someone please please tell me about finding the median by interpolation and perhaps an example of how it would could used or asked, i will be forever greatful :cool: yasmin x (i can only find a...

Find a formula to calculate G(n) and it should be a polynomial of degree 4. G(n) = 1/6(0)(0-1)(0-2) + 1/6(1)(1-1)(1-2)+...+1/6(n-1)(n-2)(n-3) I know G(0)=G(1)=G(2)=G(3)=0 G(4)=1 G(5)=1+3 G(6)=1+3+6 G(7)=1+2+3+10 G(8)=1+3+6+10+15 (sum of triangle numbers) What should I do to...
