period of a number

Graph the sine function with changes in amplitude and period. At these points (where ), the value of  is 0. If you multiply by a constant on the outside and on the inside, as in , you will affect both the amplitude and the period. Correct. Can you see a relationship between the function and the denominator in the periods? Since , the value of b could be . The period is equal to the value . 2. To help you understand changes in amplitude and period for both the sine function and cosine function, try the following interactive exercise: This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com. So . You can think of the different values of b as having an “accordion” (or a spring) effect on the graphs of sine and cosine. Here we have the number 85 to the right of the decimal point. The correct answer is A. Since it is possible for b to be a negative number, we must use in the formula to be sure the period,, is always a positive number. We can see from the graph that  goes through one full cycle on the interval , so its period is. This is the graph of a function of the form, Correct. Any one full pattern in the graph is called a cycle, and the length of an interval over which a cycle occurs is called the period. D) Incorrect. A) Incorrect. Instead of a period of 6.28 days, we'll use a period which is just 2 percent larger: 6.41 days. A)                                                                B), C)                                                                D). Notice that the height of each hill is 2, and the depth of each valley is 2. All elements in a row have the same number of electron shells. The period equals . The effect of multiplying by  is to replace y-values by their opposites. Match a sine or cosine function to its graph and vice versa. The length of this repeating pattern is, The graph below shows four repetitions of a pattern of length, If a function has a repeating pattern like sine or cosine, it is called a, You know from graphing quadratic functions of the form, Incorrect. Incorrect. Free function periodicity calculator - find periodicity of periodic functions step-by-step Regardless of the value of a, the graph must pass through the x-axis at , which it does not. However, you have confused the effect of a minus sign on the inside with a minus sign on the outside. C) The amplitude is 1, and the period is . D) The amplitude is 1, and the period is . Here is one cycle for these two functions. The correct answer is A. (It has a hill with the y-axis running through the middle.) However, in determining the graph, it appears that you switched the values of a and b. You correctly recognized the graph as a reflected sine function, but the period is incorrect. An interval of time characterized by the occurrence of a certain condition, event, or phenomenon. For this last example, you would use  and . Perhaps you saw the, Incorrect. First, observe that the graph passes through the origin, so you are looking for a function of the form . Find 52 ways to say PERIOD OF TIME, along with antonyms, related words, and example sentences at Thesaurus.com, the world's most trusted free thesaurus. The correct answer is D.   D) Correct. First, this graph has the shape of a cosine function. According to our process, once you have determined if a is positive or negative, you can always choose a positive value of b.
