निम्नलिखित फलनों के सांतत्य पर विचार कीजिए
(a) f(x) = sin x + cos x
(b) f(x) = sin x – cos x
(c) f(x) = sin x.cos x
Answers
f(x) = sin x + cos x , f(x) = sin x – cos x , f(x) = sin x.cos x संतत है
Step-by-step explanation:
f(x) = sin x + cos x
f(x) = p(x) + q(x)
p(x) = Sinx
q(x) = Cosx
Lim (x → c) f(x) = f(c)
Lim (x → c) Sinx = Sinc
f(c) = Sinc
LHS = RHS
LHL = Lim (h → 0) f(c - h) = Sin(c - h) = SincCosh - CoscSinh = Sinc
RHL Lim (h → 0) f(c - h) = Sin(c + h) = SincCosh + CoscSinh = Sinc
f(c) = Sinc
LHL = RHL = f(c)
p(x) संतत है
Lim (x → c) Cosx = Cosc
f(c) =Cosc
LHS = RHS
LHL = Lim (h → 0) f(c - h) =Cos(c - h) =CoscCosh + SincSinh = Cosc
RHL Lim (h → 0) f(c - h) = Sin(c - h) = CoscCosh - SincSinh = Cosc
f(c) = Cosc
LHL = RHL = f(c)
q(x) संतत है
p(x) + q(x) संतत है
f(x) = sin x + cos x संतत है
p(x) - q(x) संतत है
f(x) = sin x - cos x संतत है
p(x) * q(x) संतत है
f(x) = sin x * cos x संतत है
