b) Doamin of √(sinx)-(cosx)
where (.) denotes LINT

106(x) ≥ x for all x in R.... so the function has no domain.
we need (sinx) ≥ (cosx)
consider first quad..
all values satisfy. (except x=0)
consider second quad ..
all values satisfy
consider third quad...
all values satisfy (except x=3pi/2)
consider 4th quad.
no value satisfies..'
so domain
(2n pi, 2n pi + 1.5 pi)
29LINT = Least Integer Function...opposite of Greatest Integer Function..
LINT = Greater than or equal to..
so for example Lint of 2.3 = 3.... : )
