A) \[\left( \frac{2}{5},\,\,-\frac{1}{25} \right)\]
B) \[\left( \frac{1}{2},\,\,-\frac{1}{10} \right)\]
C) \[\left( \frac{3}{8},\,\,-\frac{1}{40} \right)\]
D) none of these
Correct Answer: A
Solution :
\[x=\underset{c\,\to \,1}{\mathop{Limit}}\,\frac{5\,(c-1)\,\,(c+1)}{5\,(c-1)\,\,(3c-2)}=\frac{2}{5};\] |
\[y=\underset{c\,\to \,1}{\mathop{Limit}}\,\frac{1-c}{5\,(c-1)\,\,(3c+2)}=-\frac{1}{25}\] |
