A periodic sentence has the main clause or predicate at the end. This is used for emphasis and can be persuasive by putting reasons for something at the beginning before the final point is made.
Look for and make use of structure. The narrative for this section is long, because I'm trying to include all my thinking about today's whole-class discussion.
I recommend starting by taking a look at today's Prezi and drawing your conclusions about the lesson, then reading my notes for all the details of how I enact this lesson. A lot of the lesson actually moves faster than all the words here might represent, but I try to be over-prepared for whole-class discussions, and this narrative represents a lot of that thinking.
Also, a note on voice: I slip back and forth between my "Better Lesson narrative" voice and my "teacher in the classroom" voice. I hope this provides a window into how I think when I'm putting together a lesson like this.
There are no questions, just the beginning of a sentence: I direct student attention to this slide as I return the papers they made in class yesterday. I took a look at these ledger papers, but I did not mark them in any way.
I wanted to see where students were in their understanding of yesterday's lesson, but I didn't want this to feel like an assessment.
My feedback will come in the form of pointers I offer to students as they work today. The first point I make to students is that I'd like them to carefully consider the shape of this curve and how the dots are connected. One thing I noticed when I looked at student work was that everyone was able to accurately plot the points, but the ways some of them connected the points led to some different looking graphs.
See the previous lesson for some student work samples. I say that the graph in the photograph here the axes are my work, but the graph is sketched by a student is pretty much what it should look like. I ask students to assess their own graphs for sake of comparison.
I post the learning target and ask for a volunteer to read it. Then I ask the class if there's any vocabulary they need to know. See my Strategy Folder: How to Introduce a Learning Target. I give students the chance to shout out vocabulary as they write the SLT in their notes.
To solidify our goals for today, I put up a slide with the key vocabulary, all of which students probably just read aloud. While this slide is up, I go back to the chalkboard, where I've left a note from yesterday's class that includes the slope-intercept form of a linear function, a quadratic in standard form, and the general equation for a circle.
I ask students what happens to a line if I change the value of m or b. I ask similar questions about the coefficients in a quadratic equation or in the equation of a circle. I want to be sure students notice that they have some familiarity with these equations.
Then I go back to today's vocabulary. I say that amplitude, frequency, and midline are represented by coefficients in a periodic function just like slope and y-inercept are represented by coefficients in a linear function. On the board, I write: What I'm trying to do here is establish the fact that periodic functions have all the same features as other functions students know.
They might seem a little more complicated than a line at first, but all functions share a lot of the same structure. Today's lesson really illustrates the connections between Mathematical Practices 2 and 7. By seeing the structure MP7 that all functions share, we are able to frame our work. I suppose we can think of this as a periodic teaching cycle that oscillates between these two mathematical practices.
In order to learn our way around these functions, we going to elaborate upon the mathematical model MP4 that we already started building in the previous class.A periodic function is a function that repeats its values on regular intervals or “periods.” Think of it like a heartbeat or the underlying rhythm in a song: It repeats the same activity on a steady beat.
In mathematics, a Fourier series (/ ˈ f ʊr i eɪ, -i ər /) is a way to represent a function as the sum of simple sine waves.
More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or, equivalently, complex exponentials).The discrete-time Fourier .
Much new material about periodic functions, including a new section on equations of periodic motion. 23 Nov Added quadrant numbers to a couple of the pictures. Updated the mathematical notation, particularly the use of italics and spaces, to conform to the standard.
The A stands for the amplitude of the function, or how high the function gets.
Hi, I have got some requirement like i want to run a java program to do some task between two time intervals like 10’o clock to 12’o clock everyday so please help how to accomplish my requirement any help is really appreciated. My question is how to write a periodic function in R. for example if there is a function f(x) that f(x)=f(x+4), for -2how to write it in R? thanks a lot! graphs of sine and cosine functions. • Sketch translations of the graphs of sine and cosine functions. • Use sine and cosine functions to model real-life data.

The B value is the one you use to calculate your period. The B value is the one you use to calculate your period. Write a trigonometric equation using the cosine function that best models this situation. Rewrite the equation using the sine function. For which places would the sine function be a more obvious model for the temperature data?
I want to write a function that shall execute periodic. means if i set time 1 sec that function should execute in each 1 sec.
let us call that function func1. But i dnt want to wait inside the func1 for that 1 sec.
