Vedclass · Answer

(D) Let the coordinates of point $M$ be $(h, k)$. Let $\angle MAB = 	heta$, then $\angle MBA = 2	heta$.From the coordinates of $A(-1, 0)$ and $B(2, 0)$, we have:$	an 	heta = \frac{k}{h - (-1)} = \frac{k}{h+1}$$	an(\pi - 2	heta) = \frac{k}{h-2} \implies -	an 2	heta = \frac{k}{h-2} \implies 	an 2	heta = \frac{k}{2-h}$Using the identity $	an 2	heta = \frac{2 	an 	heta}{1 - 	an^2 	heta}$, we get:$\frac{k}{2-h} = \frac{2(\frac{k}{h+1})}{1 - (\frac{k}{h+1})^2}$$\frac{k}{2-h} = \frac{2k(h+1)}{(h+1)^2 - k^2}$Assuming $k 
eq 0$, we divide by $k$:$\frac{1}{2-h} = \frac{2(h+1)}{(h+1)^2 - k^2}$$(h+1)^2 - k^2 = 2(h+1)(2-h)$$h^2 + 2h + 1 - k^2 = 2(2h - h^2 + 2 - h) = 2(-h^2 + h + 2) = -2h^2 + 2h + 4$$3h^2 - k^2 = 3$This is the equation of a hyperbola.

Let $A(-1, 0)$ and $B(2, 0)$ be two points. $A$ point $M$ moves in the plane in such a way that $\angle MBA = 2 \angle MAB$. Then, the point $M$ moves along
