Question

We are trying to graph a set of 4 equations in maple and are completely stuck with syntax. I keep on getting a "Error, invalid input: diff expects 2 or more arguments, but received 1" error. I'm hoping that you could re-write our maple script for us with the right syntax. Our equations are x(t)= 300*x(t), x"(t)=-39.68*[(x(t)/(x^2+y^2)^(3/2)], y"(t)=-39.68*[(y(t)/(x^2+y^2)^(3/2)], and y(t)=300*y(t).

Thanks ahead of time, we're really having the hardest time inputting a second order diff eq into maple!

Explanation / Answer

eq1 := diff(x(t),t,t) + 39.68*(x(t)/(x(t)^2+y(t)^2)^(3/2) = 0;

eq2 := diff(y(t),t,t) + 39.68*(x(t)/(y(t)^2+y(t)^2)^(3/2) = 0;
