Popper 19: Question 1: a. 7 4 b. 33 4 c. 4 33 33 d. 4 7
Popper 19: Question 2: a. 12 13 b. 5 13 c. 12 5 d. 5 12
Models As we know, trigonometric functions repeat their behavior. Breathing normally, brain waves during deep sleep are just a couple of examples that can be described using a sine function.
