Question

a sine curve is periodic. what does this mean? a. the curve goes through one cycle and starts over b. there is no pattern c. the amplitude stays the same d. one period equals 180 degrees please select the best answer from the choices provided o a o b o c o d

Explanation:

A periodic function, like the sine - curve, repeats its values in regular intervals. It goes through one complete cycle and then starts over again. Option b is incorrect as there is a pattern in a periodic function. Option c refers to a property of the sine - curve but not what periodicity means. Option d is incorrect because one period of the sine function is 360 degrees, not 180 degrees.

Answer:

A. the curve goes through one cycle and starts over
