Need will give brainliest 5. marco wrote the equation below. cos(-pi/2)=cos(3pi/2) which statement best describes marcos equation? a. it is true because the cosine function is odd b. it is false because the cosine function is even c. it is true because the cosine function has a period of 2pi d. it is false because the cosine function has a period of pi.

The given equation is represented below:

cos(-pi/2)=cos(3pi/2)

The value of cos(-pi/2) is 0 and the value of cos(3pi/2) is also 0

Further a function is defined as an even function if f(x) = f(-x)

Cosine function is an even function.

Therefore it is true and the correct option is c

It is true because the cosine function has a period of 2pi

Hope it helps ..!!

Option C - It is true because the cosine function has a period of .              

Step-by-step explanation:

Given :  Marco wrote the equation below.

To find : Which statement best describes Macro equation?

Solution :

Since, the period of the given cos function is 360°

So, it holds the property of trigonometric :

then the function is an even function.

Taking  

Then ,

So, the given function is a even function in a period of .

Therefore, Option C is correct.

It is true because the cosine function has a period of .
