Q.3. Solve the equations

2x + 3y + z = 9

x + 2y + 3z = 6

3x + y + 2z = 8

by LU decomposition method.

Solution.

Q.4. Fit a second degree parabola y = a + bx + cx²    in the least square method for the following data and hence estimate y at  x = 6.

X	1	2	3	4	5
Y	10	12	13	16	19

Solution.

Let us choose, X=x-3, we have y'= (∑y)/n =70/5=14

and  let  Y  =  y – y'  = 

Q.5. The population of a certain town is shown in the following table

Year X	1931	1941	1951	1961	1971

Find the rate of growth of the population in 1961.

Solution.

Here h = 10.  Since the rate of growth of population is dy/dx, we have to find dy/dx at x= 1961, which lies nearer to the end value of the table.

Hence we choose the
