Evaluation of the vector superposition of fields arising from four point-charges. This is a problem of vector addition, vector magnitudes and scalar (dot) products with a bit of trigonometry thrown in for good measure.

$f(X)$ and $g(X)$ are polynomials over $\mathbb{Z}_n$.
Find their greatest common divisor (GCD) and enter it as a monic polynomial.
Hence factorize $f(X)$ into irreducible factors.

Find their greatest common divisor (GCD) and enter as a normalized polynomial.

Question in Bill's workspace
Using Jsxgraph to draw the vector field for a differential equation of the form $\frac{dy}{dx}=f(x,y)=\sin(x-y)$, and also by moving the point $(x_0,y_0)$ you can see the solution curves going through that point.
If you want to modify $f(x,y)$ simply change the definition of $f(x,y)$ and that of the variable str in the user defined function testfield in Extensions and scripts. You have to use javascript notation for functions and powers in the definition of $f(x,y)$.
