2)Find area of region at point P satisfying maximum{PA+PB,PB+PC}<2 where A=(1/2 ,0) ,B=(3/2 , 0) ,C=(5/2 , 0)

arrey 2nd is the more easier one!!!

I thought you were asking about 1
that is why i was lazying in answering this one...

P=(x,y)
take cases..

x<1/2

1/2<x<3/2

3/2<x<5/2

x>5/2

in each case, it will boil down to

PA+PB<2 or PB+PC<2

which are ellipses!

I think you can take it from this hint

I cant think of a muchsimper/ shorter method.

Lokesh Verma ·2009-03-14 06:57:52

this is same as the area between |y|=e^-|x| and |x|<=2

This is 4 times \int_{0}^{2}{e^{-x}dx}

\int_{0}^{2}{e^{-x}dx}\\ = 1-e^{-2}

check ifthere is any mistake

tapanmast Vora ·2009-03-15 05:21:53

Sir while I was givin this one a 2nd thot I realised the questn says :

2)Find area of region at point P satisfying maximum{PA+PB,PB+PC}<2 where A=(1/2 ,0) ,B=(3/2 , 0) ,C=(5/2 , 0)

So wud not the area of favourable cases on the X-axis be jus wen 1<x<2 coz beyond this bound of X our inequality wud not hold!!

So I guess the answer and working in POST #10,11 wud be my final Ans.

Very SORRY [2] if my analysis is wrong!

*** AND ya if u chk my working pl. note that the origin has been shifted to point B

Thnx for ur relentless support [1]
