Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what does C1C2 even mean
product of their eqns ?
I think distance between centres?
hmm that would make more sense
lol this is similar to the ques u tagged me in
look at the fig carefully
is it 0
x^2 + y^2 -8y + 8 = 0
Yeah
I just realised tht
noice
u got it or should i send soln ?
Send it
ok so u want a point P on purple line such that PC1 + PC2 = minimum
we take image of C1
PC1 + PC2 = P(image of C1) + PC2
now this will be minimum then P lies on the line joining image of C1 and C2
P = (0,4) aa jayega dono lines ko solve karke
now we have centre of circle
we need radius
C1P = radius of C1 + radius of C3
c1p from dist formula
and radius of c1 from given eqn
to get radius of c3
this is root50 - root18
gandi value but square karke it becomes good
so yeah eqn of circle aa jayegi
Yo thanks for so much efforts
no problem
isi bahane acha ques solve ho gya
