Mathe Aufgaben Thema: Ganzrationale Funktionen … 11?
Ich habe also die Aufgabe einmal der wo die durch die ICH gleichung Parabel ABC Punkte gegeben geht f bestimmen! a) A (0 / 4), B (1 / 5) C (3/-5) Ich Ich muss glaube die formel y = ax ^ 2 + bx + c einsetzen Ich weiß aber nicht wie geht das genau! Danke: D i need an equation: D sorry to send it to me in yahoo america hope you could help me, D for a channel of this equation points: D THX
Ich nicht verstehen. Are you saying you need to find a parabola passing through A (0, 4), B (1, 5) and C (3, -5)? There are at least two interpolation formulas common, a Lagrange and Newton one. I'm not sure what methods you were taught. Is the "Lagrange interpolation" or "interpolation Newton's "place in the recent course material? Edit: Here is the formula of Lagrange. It's easier for me to remember. There are three points (X0, y0) (x1, y1) and (x2, y2) y = y0 * (x – x1) (x – x2) / (x0 – x1) (x0 – x2) + y1 * (x – x0) (x – x2) / (x1 – x0) (x1 – x2) + y2 * (X – x0) (x – x1) / (x2 – x0) (x2 – x1) So, for you would be y = 4 * (x – 1) (x – 3) / (-1) (-3) + 5 * (x – 0) (x – 3) / (1) -2 () – 5 * (x – 0) (x – 1) / (3) (2) = (4 / 3) (x – 1) (x – 3) – (5 / 2) x (x-3) – (5 / 6) x (x – 1) must be simplified, but that is the method. As I said, there is another method due to Newton.
