Question

consider the function f is defined as f(x)=sin4+sin3x+sin2x+cos4x+cos3x+cos2x find the domain

Answer 1

Domain refers to all those values of x for which function is define.

we know that sinx and cosx both are defined for every real values.

Hence, The domain of the given function f(x) is all real numbers.

I hope you will get it.
