There are some minor changes in the graphs' line widths and text sizes.įunction plot types no longer omit portions of a curve for some graphs. This prevents the interface from getting stuck in unintended long-running calculations. Implicit plots and slope fields are no longer options for a semi-log grid. The y-axes of semi-log plots are now labeled with typographical exponents, e.g., 10 3 instead of 10^3. This better matches the practice seen in most textbooks, etc. Html entities for special characters are now replaced with their corresponding special characters as you type. For example, if your viewing window has x ∈, the y-axis will appear on the left, and a broken axis symbol will show that the x-axis is broken between 0 and 5.Īll text entry fields now have a button to clear the current entry. You can now place captions either above or below the graph.īroken axes are now represented as such. But this….well….this, I got nothing….You can now choose the color of captions. Most of the time, I can explain those terms, and why people would end up here. Would enjoy your input!Īnd finally, I started this post by sharing some of the search terms which cause people to find my blog. But my early impression is that it is a addition which works seamlessly with the existing, awesome, calculator.Īlso, while I’m in a sharing mood, here is a quick file I created to use in an absolute value inequality unit. The Desmos folks tend to monitor these things, so let’s see if they have a suggestion here.ĭown the road, I want to take a deeper look at the new table feature, and will report out. Let’s graph this function:Ĭlick this link to find out what happened when I tried to enter this function on Desmos. Something neat (odd, goofy) happens when an equals is used in the domain restrictions. OK, smart guy, yes…yes, I have kinda avoided the equals parts of the domain restrictions.
SO, WHY ARE YOU AVOIDING “EQUALS” IN YOUR FUNCTIONS? The sharing features are another aspect of Desmos which have improved greatly in the past year. Click the icon below to play with the document online. Then, a can be used in the piecewise function. For mine, I chose to limit the domain to between -10 and 10, and have step counts of. In Desmos, start by defining a slider for the parameter “a”. Consider this problem:įor what value(s) of x is the piecewise function below continuous? Sliders can be used to have students explore the continuity of a piecewise function. So, the piecewise function above would be entered as: And commas are used to have multiple function rules in one command. In the Desmos calculator, colons are used to separate domain restrictions from their functions. Let’s say we want to graph this piecewise function: But I’ll provide a few examples here, and some teaching tips. The Desmos knowledge base provides instructions for graphing a piecewise function, and a neat video tutorial.

Let is never be said that mathcoachblog doesn’t listen to the needs of its followers! One of the neat things about having a blog is checking out the routes people take to get to the blog. UPDATE: Many of my Desmos files are avilable on this page: Desmos File Cabinet Enjoy! NEW: After popular demand from this post, I have created a tutorial on domain restrictions and piecewise functions.
