f के सांतत्य की जाँच कीजिए, जहाँ f निम्नलिखित प्रकार से परिभाषित हैf(x) = \left \{ {{sin x-cos x } यदि x \neq 0 \atop {-1} यदि x = 0 } \right
Answers
f(x) संतत है x ∈ R
Step-by-step explanation:
f(x) = Sinx - Cosx यदि x ≠ 0
-1 यदि x = 0
x ≠ 0
f(x) = Sinx - Cosx
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
x =0 , संतत है यदि
LHL = RHL = f(0)
LHL = Lim (h → 0) f(0 - h) = Sin(-h) - Cos(-h) = - 1
RHL = Lim (h → 0) f(0 + h) = Sin(h) - Cos(h) = - 1
f(0) = - 1
LHL = RHL = f(0)
f(x) , x = 0 पर संतत है
f(x) संतत है x ∈ R
और जानें:
फलन f(x) = 5x – 3, x = 0, x = – 3 तथा x = 5 पर संतत है
