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.im getting A=-4, B=1, D=2
aage kaar raha hun
is the ans ab?
@hardcoreisdead
yepp
yea btao kaha dikkat ha ab
and if possible see the alc phen doubts too bro
given my ans , everywhere
bc itna galat kaise aa rha hai
will do soon
me when chemistry
dekho jo double derivative ha
usme se ek factor kat jayega
c^2x -cx +1 bachega
isko do baar derivate kardo
baaki to limit hi nikalni ha vo to easy hi ha
exact yhi kia hai
cos^2x - cosx +1 =y
y'= -sin2x + sinx
y' = -cos2x/2 + cosx = (2cosx-cos2x)/2
right?
2cosx-2cos^2x+1)/2
-cos^2x+cosx+1/2
differentiaion mei to numerator mein lete constant
bro isnt a=-1, b=-4, c=0, d =ln3
ismein galti bata do
idk yaar differemtiation kraayi hame
'pehle se aati hogi'
han toh aati hogi na
š
basic math jitni aati h
uss se jyada nahi lag rhi
howd u get this tho
use expansion
š
aint no way am doing that
šØ
are usme bhi kuch nahi karna
bas constant 0 karna ha
c must be 0 otherwise infinite ho jaayegi
bhai tu differentiation mein galti batade
send differentition pls
ye
what?
oh
1^infinity form hai na
nvm nvm bruh im dumb
vo -cos2x/2 glt ha, -2cos2x ayega
this will tend to 0 when c =0
Kya galat hai
š
bro cant beleive i left this ques
š
same batch mei ho kya?
no but same coaching
abe c ko 0 nahi hona padega if we want finite limit
company
oh han bc makes sense
e^(c/x^2 + d )
hua
tune d hi gayab krdia
d=ln3
maybe u confused x to be nfinity
haan ab bani na baat
ek sec
0 ki kara
bc c=0 kyu
x infinity thodi hai
otherwise c/x^2 wont be finite
hein
continuous nahi rhega fir
yh tending to 0 hai na
only case its finite is when c=0 so 0/very small qty = 0
okk
got that part
a b aur bata do
wdym
hein
small a small b
A B nahi
-1,-4
kaise aayega
one eqn i got was a+b=-5
dekh pehli limit mein
just put expansion
meine fir 2 baar l hopital lagaya
haan sahi ha
kyuun
2a-b= 6 aaya
yes second one me x^2 ki terms ko equate kro 3 se
0/0 form
haan chal theek ha
limit 3 hai na
-2a-b=6 aana chahiye
yep
bcz hmara bina l hoptial ke a-b/2=3 aya tha
š„
thanx for bearing with me
bc itna kaise hag dia
always
beech paper jab koi dhoka dega toh pata chalega

+solved @Prasan @Imine
are kya hogya
