This assignment has eight problems of 40 marks, each of 5 marks. All problems are compulsory. 10 marks are for viva voce. Please go through the guidelines regarding assignments given in the programme guide for the format of presentation.

Q1. Write a program in C that accepts a decimal number and displays its floating-point equivalent number. You may make assumptions to simplify the program, however, your representation of floating point number should be closer to IEEE 754 standard 32 bit representation.

Q2. Write a program in C to implement Regula-Falsi method.

Q3. Write a program to implement Gauss Elimination method for solving linear equations. Your method should check if a given pivot is zero or not. It should also minimise the floating-point errors.

Q4. Write a program in C for the demonstration of Stirling's Formula for Interpolation.

Q5. Write a C Program for solving the following system of equations using Jacobi method:

$egin{bmatrix}5&-1&-1&-1\-1&10&-1&-1\-1&-1&5&-1\-1&-1&-1&10end{bmatrix}egin{bmatrix}x_1\x_2\x_3\x_4end{bmatrix}=egin{bmatrix}-4\12\8\34end{bmatrix}$

Starting with $\text{x}^{(0)} = (0, 0, 0, 0)$ . The exact solution is $\text{x} = (1, 2, 3, 4) \text{T}^\text{n}$ .

Q6. Write a C program to solve the IVP $y' = -ty^2$ , $y(2) = 1$ and find y(2.1) and y(2.2) with $h = 0.1$ using improved tangent method (modified Euler method) of O(h²) .

Q7. Write a program in C to find the approximate value of the following definite integral using Trapezoidal rule and obtain a bound for the error. The exact value of $I = \ln_2 = 0.693147$ correct to six decimal places.:

$$ \int_{0}^{1} \frac{dx}{1+x}$ $

Q8. Write a program in C to solve the equation $x^2y' = 1-xy-x^2y^2$ , $y(1) =-1$ from $x=1$ to $x=2$ by using Taylor series method of O(h²) with $h= 1/3$ and 1/4 and find the actual error at $x=2$ if the exact solution is $y=-1/x$ .
