Periodicity of cosine
WebTrigonometric Periodicity Identities. The period of a function is the smallest amount it can be shifted while remaining the same function. In more formal terms, it is the smallest p p such that f (n+p)=f (n) f (n+p) = f (n) for all n n. Intuitively, the period is a measure of a … Webcos and sin both have period $4\theta$. For part (b), you have to determine the period numerically in general. Of course the answer is $2\pi$, but proving this depends on what your definition of $\pi$ is. A popular definition is that $\pi$ is simply twice the smallest positive $\theta$ such that $\cos(\theta)=0$, in which case period $2\pi$ is ...

So, for a given change in x, cos (2x) completes more cycles than cos (x).
