If f.g is continuous at x = a, then f and g are separately continuous at x = a.
विकल्प
True
False
उत्तर
This statement is False.
Explanation:
Let us take an example: f(x) = sin x and g(x) = cot x
∴ f(x).g(x) = sinx . cotx
= `sin x * cosx/sinx`
= = cos x
Which is continuous at x = 0 but cot x is not continuous at x = 0.
