• Make sure you have completed all Desmos Activities up until this point, including the Desmos Activity "128 Day 03 - Exploring Functions with Sliders".
• Meet for at least one hour outside of classtime with at least one other classmate. Your goal is to get together to discuss being creative with Desmos and work to help each other complete the two tasks below. Feel free to use Discord to find a partner (or partners) to work with.
   
  After your meeting write one paragraph about something that you learned or experienced that you would not have if you had worked alone. Also write down the name of the person you met with and when you met! I will collect this paragraph in class.
   
• Task 1. Make functions that have certain properties. Open a new Desmos worksheet. (Remember to log in!) In the first cell of the worksheet, write your name in a "note" cell. Now, given the experience you gained in class, try to create graphs of five functions whose graphs have the following properties. Feel free to be as creative as possible. When you have finished, open the Share Dialog, copy the URL that was generated, and submit that URL in this form.
1. A line that looks almost vertical.
2. A graph with a sharp corner.
3. A graph with exactly four bumps.
4. Steps going downward.
5. A graph that has waves like the ocean but wiggles right and left instead of up and down.


• Task 2. Be creative with parent functions. Choose at least three different parent functions and at least one implicit function to explore. Type them into your Desmos worksheet and introduce sliders for coefficients, powers, and whatever else you can think to add. Move the sliders until the functions are interesting to you. Make sure you record the values of the sliders and the formula including the numbers (and not variable names) that gave you the graph you liked best.
   
  Export and Share your favorite function(s) to our class Discord Server (like you did on last Thursday) in the Daily Question for February 7 thread in the #functions channel. Explain in a few sentences what about your example you liked.

• Make sure you have completed all Desmos Activities up until this point, including all the Desmos Activities from Day 04.
• Practice the techniques from Tuesday's activities with an eye toward creating something you might use for the first project. Do the following.
1. Find a function whose graph has a shape you like.
2. Restrict the domain of your function so you have a "snippet" of the graph.
3. Insert h and k's into your equation(s) so that you are able to translate the "snippet" using a slider. Make sure the slider works correctly.
4. Delete the slider cells. Replace them by new cells that define h and k as lists instead.
• (By the way, I highly recommend working together with classmates on this task!!! It will be helpful to have input from someone else who is working on something similar, in order to ask each other questions as you go along.)
• Export and Share your resulting picture and Desmos notebook to our class Discord Server (like you did on last Thursday) in the Daily Question for February 9 thread in the #translations channel. Explain in a few sentences what about your example you liked.

• Makerspace Orientation
• AxiDraw Orientation
• Inkscape Tutorial

• You are going to start working on Project 1 in earnest. Complete the following steps to build the basis of your artwork.
• Your goal is to draft three different initial sketches that could form the basis for your final piece of art.
• You can start these sketches on paper if you like, however it is very important that you work to translate your ideas into mathematical functions and display them in Desmos.
• You may find it helpful to think about the visual properties you are going for in your sketches, similar to the list of terms we crowdsourced. Feel free to use the resources above to find some words to describe the properties that you want to explore. Write those words down so you can remember them later. (More words: HERE, HERE, HERE.)
• You should use Desmos as a sketchpad. Start off with a parent function (or a couple), and use the techniques from class to modify and combine the functions to a desired shape and size. Introduce sliders to to modify your parameters so that they are exactly where you want them to be.
• Once you have an initial shape that works for you, save the notebook. You should be creating many different notebooks, one for each seed of the drawings you wish to explore.
• Once you have tweaked your sketches sufficiently that you are happy that each sketch matches the idea you are aiming for, export the three sketches to five SVG files, NOT PNG files. We went over this in class, and here is a video that shows those steps again: (Exporting your artwork to SVG.)
• Bring these to class. I am expecting THREE draft artworks from every person, each with its own style. We will share and discuss these together in class.
• As part of your project lab report, you will be reflecting on the creative process of coming up with the ideas from your artwork. Write at least one paragraph (5–7 sentences) about what you experienced, or what was difficult, or the process you used to complete these first steps. Save this paragraph on your own computer so that you can use it during your writeup. Then submit it here before class.

• Practice the techniques from Thursday's activities. Do the following.
1. Start with a function or implicit function you have never used before.
2. Introduce coefficients and restrict the domain as necessary to that you have a "snippet" of a graph that is pleasing to your eye.
3. Now create a transformed copy of this "snippet": Insert a's, b's, h's, and k's into your equation(s) so that you are able to transform the "snippet" using a slider. Make sure the slider works correctly.
4. Arrange the original curve with the transformed curve so that they align in a way you are satisfied.
5. Do this again to make a third copy of the curve.
6. Do this at least one more time so you have at least four transformed copies of your original curve together on the same picture.
• Share an image of your final result along with your notebook in the #multiple-transformations channel on Discord.

2. Plot f(x)+g(x), f(x)+h(x), and g(x)+h(x), then f(x)*g(x), f(x)*h(x), and g(x)*h(x), then find an interesting division and and interesting composition to share.
• Share an image of your final result along with your notebook in the #combining-functions channel on Discord.

• Exploration of The Unit Circle. Pay particular attention to:

• How if we draw the behavior of the y-coordinate as a function of theta we get y=sin(θ)
• Discussion of Polar Coordinates. Pay particular attention to:
• How in Cartesian Coordinates, a point is represented by a horizontal displacement x and a vertical displacement y. Every point has a unique (x,y) pair.
• How in Polar Coordinates is represented by a distance to the origin r and an angle θ.
• Every point has many (r,θ) pairs.
• Practice this together: "128 Day 12 - Polar Coordinates Practice"
• Discussion of Polar Graphs. Pay particular attention to:
• When we draw the graph of y=f(x) using Cartesian Coordinates, we change our value of x and determine how far above or below the x-axis the dot is placed based on f(x).
• When we draw the graph of r=f(θ) using Polar Coordinates, we change the value of our angle θ and determine how far in the direction of θ the dot is placed based on f(θ).

1. Develop a polar curve of your own choosing. You may wish to start with a curve from our Desmos Activity "Day 12: Polar Equations Investigations" or the Fifty Famous Curves pdf.
2. Next, introduce parameters to modify the shape so that it is how you want it to be.
3. Then, apply some transformations to the shape, either by translating, dilating, or combining it with another function.
4. Last, Add a second, complementary curve to your image to complete the artwork. This complementary curve can either be a standard function y=f(x), an implicit function, or another polar function.
5. There should only be two (carefully crafted) curves in your final image.
