your doubt
or for others practice ?

doubt hai mahraaaaaaaz
meko nahin aata[2]

ok well its quite straight unless i am missing something

βsinβ + (Ï€/4)cosβ +√2β = _Ï€/4∫^β f(x)dx

which means
βcosβ + sinβ - (π/4)sinβ + √2 = f(β)

answer seems to be
(b) [1]

[339]

yar susti mein hoon
ek baar pad ke aaya nai to pooch lia

THANX 4 THE HELP
