Question

What is the period of the function? y=2 cos pi x

Answer 1

 The period is the distance required for the function to complete one full cycle. The period is 2π/B where B in this case is equal to 1. Therefore, the period of the function is 2π. Hope this answers the question. Have a nice day.

Answer 2

Answer:

Step-by-step explanation:

Alright, lets get started.

The given function is : $y=2cos(\pi x)$

As per the standard one, the cos function is : $y=cos(bx+c)$

When we compare our function with standard one,

a is 2

b is π

c is 0

The formula for period is : $\frac{2\pi }{b}$

Plugging the value of b, the period is : $\frac{2\pi }{\pi }=2$

Hence the period is 2    :    Answer
