I am trying to understand the true or exact value of cosine, not just an approximation. I want to know the precise mathematical value that defines cosine in trigonometry and its applications.

I'm trying to understand trigonometric functions, specifically the cosine function. I know it has a range from -1 to 1, but I'm confused about what exactly the negative value of cosine represents. Can someone explain this to me?

I'm wondering if there's a maximum value for the cosine function. I know cosine is a trigonometric function, but I'm not sure if it has a defined upper limit or if it can go up to a certain point and no further.
