Question

Use Euler's method with h = 0.2 to approximate thesolution of the differential equation
dy/dx = xy with y(0)=2.0 at x = 1.

Note: your answer must agree with the computed answer to at least 3digits. You should enter at least 4 or 5 digits. If an answerterminates in an exact answer, e.g. 1.50, then enter this answereven if it is fewer than the indicated number of digits.

Explanation / Answer

h=0.2;

tmax=1.0;

t(1)= 0;

n=(tmax-t(1))/h;

y(1)=2;

tout=t(1);

yout=y(1).';

disp(' tiEULER')

disp('~~~~~~~~~~~~~~~~~~~~~~~')

for i=1:(n+1)

t(i+1)=t(1)+i*h;

%

k1=h*f(t(i),y(i));

y(i+1)=y(i)+k1;

%

tout=[tout;t(i)];

yout=[yout,y(i).'];

fprintf ('%5.2f%17.4f ',t(i),y(i));

end

function yz=f(t,y)

yz=t*y;
