The normal at the point $(1,1)$ on the curve $2 y+x^{2}=3$ is (A) $x+y=0$ (B) $x-y=0$ (C) $x+y+1=0$ (D) $x-y=1$
Application of Derivatives
Maxima and Minima
The normal to the curve, $x^{2}+2 x y-3 y^{2}=0$, at $(1,1):$ $[2015 \mid$ (A) meets the curve again in the second quadrant. (B) meets the curve again in the third quadrant. (C) meets the curve again in the fourth quadrant. (D) does not meet the curve again.
The normal at any point $P\left(c t, \frac{c}{t}\right)$ on the curve $x y=c^{2}$ meets the curve at $Q\left(c t_{1}, \frac{c}{t_{1}}\right)$ then $t_{1}$ is (a) $-t$ (b) $\frac{1}{t^{2}}$ (c) $-\frac{1}{t^{3}}$ (d) None
