This problem can be easily computed with the help of programming .
i'm using c++ code for computing this
here is the code which can be used for finding the solution
#include<iostream>
using namespace std;
double calFunc(double x,double y)
{
double res=x*x - (1/y);
return res;
}
int main()
{
double x0=0, y0=11,x1=0.2, y1=22;
double finalY=0;
double h=0.2;
for(int i=2;i<=99;i++)
{
finalY=y1+ h* (5*calFunc(x1,y1)/12+2*calFunc(x0,y0)/3 );
x0=x1;
y0=y1;
x1+=0.2;
y1=finalY;
cout<<"\ny"<<i<<": "<<finalY;
}
}
and the output associated is :
as we can see that y99 is 2731.29 which will be 2731 when rounded off to nearest integer.
I hope this will help you so please give positive ratings :)))

3 MARKS QUESTION 3 Background The van der Pol equation is a 2nd-order ODE that describes self-sustaining oscillations in which energy is withdrawn from large oscillations and fed into the small oscillations. This equation typically models electronic circuits containing vacuum tubes. The van der Pol equation is: dt2 dt where y represents the position coordinate, t is time, and u is a damping coefficient The 2nd-order ODE can be solved as a set of 1st-order ODEs,...
