Question

period of cos(7x-5)​

Answer 1

The period of cos is equal to x2

Answer 2

Answer:

$\dfrac{2.\pi}{7}$

Step-by-step explanation:

We have to find the period of cos(7x-5)​

The period of any periodic function is the value of x (angle) after which the value of function start repeating itself.

Since the period of sinx or cosx is 2π.

and to find the period of any sin or cosine function in the form of cos(ax+ b), we have formula$\ \dfrac{2\pi}{a}$.

hence, the period of  cos(7x-5)​ = 2π/7
