11is the line y=3x+1
or y+3x+1=0
Equation of a parabola is
x2-y2=100
Find the nearest point on this hyperbola to the line
y+3x+1=0
you first solve this .. then i will tell the fallacy!

No common normal here...
therefore by the method of "all questions given now are solvable" and "in exams there is time limit"...
I think answer will be ...
shortest distance is distance between (-10,0) and foot of perpendicular from it on line which is same as distance between (10,0) and foot of perpendicular on line..
62what can i do if people are as smart as u are celestine...
U killed my fallacy ;) :P
9abishek can u be more elaborate on ur method i cudnt understand that pls explain ;)
method of "all questions given now are solvable" and "in exams there is time limit"...
9but then wat fallacy is there to kill , i thouht it was straightforward
62basically FIITJEE had solved this question incorrectly
and I could see why they had done that....
They found out wrong theta.. (a sec theta, b tan theta)
So they got a wrong answer...
Basically their answer was in the 4th Quadrant! which many ppl wud get!
9yes i had to consider only one theta other one will give local minima but not global minima ;)
