Write a program in jupyter notebook to integrate up to four sets of coupled differential equations using the Euler method.

Then use this program to solve the equation below.Thank you.

2. Use your program to solve the differential equation for x(t): dt2 + x = 0; with the initial conditions x(0) = 1, x'(0) = 0. Note that this has the analytical solution: x = cos(t) (a) Integrate the equation for 0
