Presentation Transcript

  1. 7.4D-Calculator for Row Operations • Enter matrix 2nd, (MATRX), → Edit: size (R x C), entries • Home screen 2nd, MODE (QUIT) • Perform row operations 2nd, MATH, choose operations

  2. Row operations • Make an augmented matrix out of 2 matrices 7: augment(NAME, NAME) • Switch 2 rows C: rowSwap (NAME, first row, second row) • Add 2 rows (already opposites) D: row+(NAME, first row, second row) • Multiply a row by a number E: *row(# mult. by, NAME , row) • Multiply a row by a number & add to another F: *row+ (# mult. by, NAME, row mult., row added to)

  3. More Row Operations • Put in ROW ECHELON Form A: ref(NAME) • Put in REDUCED ROW ECHELON Form B: rref(NAME) • HELPFUL if entire system entered as non-square system before finding ref or rref .

  4. Applications (Use calc) • 1. Set up a linear system and find the quadratic model y=with an augmented matrix and a calculator for f(-2) = -15 f(-1) = 7 f(1) = -3

  5. Application • Set up a system of equations and solve to find the cubic model y= for F(-2)=-7 F(-1)=2 F(1)=-4 F(2)=-7
