The equation of normal to the curve y = `log_(e)` x at the point P( 1, 0) is ..... .A. 2x+y=2B. x-2y=1C. x-y=1D. x+y=1 |

Answer» Correct Answer - D We have, y`=log_(e)xrArr(dy)/(dx)=1/x` `therefore` Slope of normal at P(1,0) `=-1/((dy//dx)_((1,0)))` `=(-1)/1`=-1 `therefore` Equation of normal at P(1,0) `rArry-0=(-1)(x-1)` `rArry=-x+1` `rArrx+y=1` |
