[填空题]
Consider the curve yj *hvh+ slu7o9ztk-d4 1 y7 j;9j3eyx q- a(qo,gzisxx=$\frac{12x}{1+4x}$ , x∈R, x≠−1.

1.Find $\frac{dy}{dx}$.
$\frac{dy}{dx}$=$\frac{a}{(1+4x)^2}$; a=  .

2.Determine the equation of the normal to the curve at the point P(−1,4).
hence, we get y=-$\frac{3}{4}$x+$\frac{a}{b}$ ;a=  , b=  .
