Hi I am trying to solve couple differential equation.I dont understand in which way I can solve.Please help

clear all;
a=2.132e14;
b=25.715;
c=9.79e-3;
d=3.14e-3;
e=12.56e-3;
f=3.14e-3;
g=12.56e-3;
h=8.8e8;
i=2.1994e8;
j=3.59e8;
diff(u) ==(a/(tan(u).^2+b/cos(u).^2))*(-tan(u)*(c+d*cos(v-u)+e*cos(2*(v-u).^2))-f*sin(v-u)-g*sin(2*(v-u)))
diff(v) == h*sin(2*(v-u))+i*sin(v-u)-j*cos(v)

Take a look at the examples provided on how to use MATLAB's "ode45".

Best wishes

You can also solve it using the symbolic math toolbox:
