Marco wrote the equation below. Cos ( -π /2) = cos ( 3π / 2)

Which statement best describes Marcos equation?

Answer:

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

Step-by-step explanation:

Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:

$Cos(\theta)=Cos(2\pi +\theta)$

Taking $\theta$ as $-(\pi)/(2)$ , $(2\pi + \theta)$ is equal to $2\pi + (-(\pi)/(2))\n=2\pi - (\pi)/(2)\n=(4\pi-\pi)/(2)\n=(3\pi)/(2)$

The equation is true!

Note: The cos function is even function

Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
