Question

The period of the function f(x) = cos4x + tan3x is ____________.

Options

• None of these

• ${\displaystyle \pi }$

• ${\displaystyle \frac{\pi }{3}}$

• ${\displaystyle \frac{\pi }{2}}$

Answer 1

The period of the function f(x) = cos4x + tan3x is ${\displaystyle \underline{\pi }}$.

Explanation:

${\displaystyle f\left(\pi \right)=(\text{cos} 4\pi +\text{tan} 3\pi )}$ gives the same value as f (0).Therefore, the period of the function is ${\displaystyle \pi }$
