Trapezoidal Method Algorithm

  • Start
  • Define and Declare the function
  • Input initial boundary value, final boundary value and length of interval
  • Calculate number of strips, n=(final boundary value-initial boundary value)/length of interval
  • Perform the following operations in loop
    y[i]=f(x[i])print y[i]
  • Initialize se=0,s0=0
  • Do the following using a loop
    if i%2=0
  • ans=h/3*(y[0]+y[n]+4*s0+2*se)
  • print the ans
  • stop
