Matlab code

%% #6 % % WRITE CODE BELOW: % Define the anonymous function % df(t,y) = [-y(2)+y(1)*(y(1)^2+y(2)^2) * sin(pi/sqrt(y(1)^2+y(2)^2)); % y(1)+y(2)*(y(1)^2+y(2)^2) * sin(pi/sqrt(y(1)^2+y(2)^2))] % Use ode45 to solve this equation on the interval [0,10] with the initial % condition [0.5;0.5]. From the solution [t,f], plot column 1 of f as your % x values and column 2 of f as your y values. % (Your solution should look like a spiral closing into a circle) % %
