Attempt 5 ques. in all,
choosing 1 ques. from every unit.

UNIT-I

1. How a floating point number is stored in the memory of a computer? explain with examples the procedures of 4 basic arithmetic operations using normalized floating point numbers. 10

OR

2. What do you mean by roots of an equation? explain the successive bisection method of evaluating roots of a non-linear formula in 1 variable. Develop the algorithm of the method. 10

UNIT 2

3.. explain the Gauss Seidel method for the solution of simultaneous equations. What is Pivoting? discuss its use in Gauss Seidel Method. provide a comparison of direct and iterative methods. 2+4+4

OR

4. explain the Gauss elimination method of solving simultaneous linear equations. Develop the algorithm for the method. 4+3+3

UNIT 3

5 . discuss the Euler's method of solving ordinary differential equations. Develop the algorithm of the method. explain the fault in the Euler's method. 10

OR

6. Using Runge-Kutta 4th order method obtain the solution of the subsequent ordinary differential formula at x=0.4 the intial values are y=1 at x=0. Use the steps of size 0.2. 10

dx/dy=x+y2


UNIT 4

7. What is difference table ? Construct a difference table from the subsequent data and hence using the polynomial interpolation obtain the value of function f(x) at x= 2.0 :- 10

X f (x)
-1.0 3.0
0.0 5.0
1.0 1.0
3.0 -1.0
1.0 13.0

OR

8. explain the method of approximating a function by using Chebyshev series. Use this
method to approximate the series expansion of sin (x) for 3 digits accuracy. 10

UNIT 5

9 . discuss the method of numerical differentiation. explain the fault in the differentiation formulae. Using this method obtain the differential of function f(x) at x = 1.3 from the subsequent tabulated data :- 3+2+5

X f(x)
1.0 0.0
1.2 0.365
1.4 0.673
