replace a differential equation by an equivalent system of first order equations:
If a particle of mass $m$ moves in the $x$-$y$ plane, then its equations of motion are
$$m\frac{d^2x}{dt^2}=f(t,x,y)\space \space \text{and} \space \space m\frac{d^2y}{dt^2}=g(t,x,y).$$
Here $f$ ...

Find the derivative of $F =$ $(GmM)\over r^2$
Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass M on a body of mass m is
$F =$ $(GmM)\over r^2$
Where G is the gravitational constant and r is the ...

Is it possible to formulate variational calculus geometrically?
In textbooks I've seen differential geometry is done with finite-dimensional manifolds. Is it possible to generalise to banach manifolds so as to formulate the calculus of variations within it, or ...
