प्रथम सिद्धांत से फलन f(x) का अवकलज ज्ञात कीजिये जहाँ `f(x) = sin x + cos x`.

फलन f(x) पर अवकलनीयता

The function f(x) = sin x + cos x will be

The range of f(x) = cos x - sin x is

The range of f(x)=cos x-sin x is

Period of f(x)=sin((cos x)+x) is

Discuss the continuity of the following functions: (a) f(x) = sin x + cos x (b) f(x) = sin x - cos x (c) f(x) = sin x . cos x

If f(x)=2x+[x]+sin x cos x, Then f is:

Prove that f(x) = sin x and f(x) = cos x are continuous.
