static double Britbot.Navigator.SolveStupidEquation	(	double	a,
		double	b,
		double	c,
		double	d,
		double	e
	)		`[inline, static]`

This function should solve equation (*) in calculation sheet 2 I am not sure if this works, the solution was annoying as hell, hope i did everything right.

Parameters:

a	\|d\|_{1}
b	t_{x} - u_{x}
c	d_{x}
d	t_{y} - u_{y}
e	d_{y}

Returns:
