## anonymous one year ago the cosine function is an odd function? true or false?

1. SolomonZelman

apple can be blue true or false

Even functions are defined by: $$f(-\theta) = f(\theta)$$ Odd functions are defined by: $$f(-\theta) = -f(\theta)$$

3. Jhannybean

That means if you plug a negative value in fr your function of cosine, and you get an even result, then your function is even, and plugging in a negative value into your function resulting in a negative result means your function is odd.
