IGNOU BCSL-058-Computer Oriented Numerical Techniques Lab, Latest Solved Assignment (July 2023 - January 2024 )


Q5. Write a C/C++ program that approximates the solution of the initial value problem: y’ = f(t, y) with y(a) =y0over[a, b] using Euler’s method. Using the program approximate the solution of the initial value problem: y’ = -2ty^2 withy(0) =1

#include <stdio.h>

// Define the function f(t, y) = -2ty^2
   double f(double t, double y) {
       return -2 * t * y * y;

// Euler’s method for solving the initial value problem void eulerMethod(double a, double b, double h, double y0) {
      double t = a;
      double y = y0;

      printf(“t = %lf, y = %lf\n”, t, y);

     while (t < b) {
             y = y + h * f(t, y);
             t = t + h;
             printf(“t = %lf, y = %lf\n”, t, y);

int main() {
double a = 0.0;           // Initial value of t (a) 
double b = 1.0;         // Final value of t (b)
double h = 0.1;        // Step size
double y0 = 1.0;     // Initial value of y (y(a))

printf(“Approximate solution using Euler’s method:\n”);
eulerMethod(a, b, h, y0);

return 0;
