When T tridiagonal. Its L and U factors have only two nonzero diagonals. How would you take advantage of knowing the zeros in T, in a code for Gaussian elimination? Find L and U. Tradiagonal T=[1200 2310 0120 0034].

Part a)  product a is decreasing by 18% per year1 - .18 = .82part b)  which product recorded a greater percentage change in price over the previous year?   product b recorded a greater percentage change.  justify your answer: the equation for product b is  y= 10000(.56)^x , and 1 - .44 = .56product b decreases by 44% per year

  example you can find the perimeter by addig all of its respective sides as such: (12+x)+(12+x)+(7+y)+(7+y).  adding like terms will result in   2x+2y+38    if you chose  xy+7x+12y+84, you multiplied the two sides to find the area.  if you chose  x+y+19
