In Mathematics‚ a periodic function is a function that repeats its values in regular intervals or periods. Periodic functions are used throughout science to describe oscillations‚ waves‚ and other phenomena that exhibit periodicity. Periodic functions are those that repeat on a set interval. All trigonometric functions are periodic. They are useful because one can determine the value of the function anywhere in the domain. If a function is periodic‚ then there is some value n for which

+ 36 from both sides x² - 8x - 20 = 0 factor the quadratic equation (x -10)(x + 2) = 0 use zero factor property to solve X – 10 = 0 or x + 2 = 0 creating a compound equation x = 10 or x = -2 the answer cannot be – 2 x = 10 Now we will plug in the value and solve: x paces north and 2x + 4 paces east or 10 paces north and 2(10) + 4 = 24 paces east of Leaning Rock.
