Question
Graph the functions in Exercises $13-22 .$ What is the period of each function? $\sin 2 x$S$\cos \pi x$S
Step 1
The cosine function, $\cos x$, has a period of $2\pi$. This means that the function repeats its values every $2\pi$ units. The amplitude of the function is 1, which is the maximum value of the function. Show more…
