Question

2. The Period of sin ,cos ,sec ,cos x x x ecx is
1.f/2
2.f
3.3f/2
4.2f​

Answer 1

Answer:

Correct option isD 2π

Consider the given function sin(cosx)+cos(sinx)

We know that period of sinx and cos x is 2π

The period of a function of type f(g(x)) (composite function )is the same as the

Period of the g(x)

And the period of a function h(x)=f(x)+g(x) is the LCM of the periodic function f(x)and g(x)

So,

Applying the above two, period is LCM of 2π,2π which is 2π.

so, 2π is the right Answer ✌️
