hehehehe... GP bro it was fun reading your comment again. you used your gx/gy logic "to make big things vanish part by part" but the same Differential Equations can be used other way; dy/dx = 2x ? dy/dx = 3y2 or dy/dx = 3(x/y) ? dy/dx = 0.5x+y. Assuming Nepal as Dy. unfortunately, matrix calculus doesn't apply in politics.
