Undo and redo actions

You can now make mistakes without having to start all over again. We added Undo and Redo buttons to make the board easier and more user-friendly to navigate.

The icons are located in the top-left corner of the navigation bar, but you can also use Ctrl + Z (Cmd + Z on Mac) and Ctrl + Y (Cmd + Shift + Z on Mac) for a smoother workflow.

Templates for graphs and equations

We added templates for Grapher cards. You can now quickly plot polar curves, conics, inverse functions, or equations with variables. Never get lost starting from scratch again!

We also introduced templates in Equation cards, quickly solve polynomial equations or systems of equations. Never get lost by not knowing what to write!

Find coordinates

Grapher cards now include a find coordinates option in the More menu. This feature allows you to input an x or y-value to find associated points on your curve.

Also provided is a draggable vertical or horizontal line, perfect for exploring domain and range, intervals of increasing and decreasing and so much more!

Make a prediction for regression

In Regression cards, you can now use the button in the top-left corner of the graph to make a prediction given the model ŷ or the value of x. Simply choose your known value, x or ŷ, input your value and find the associated prediction on the model.

Also provided is a vertical or horizontal line that can be dragged for more exploration.

Analyze polar functions

You can now better analyze your polar functions. When hovering over any point on the graph, you can display r-derivatives as well as the exact x and y coordinates.

You can also find coordinates based on a specific value of θ (showing r, x and y for each value), and display the tangent line along with its equation, slope, and corresponding r value.

Remember inference parameters

After performing a Significance test or Confidence interval, you can quickly change to the other and all selections and inputs carry over.

Selections and values you input are also remembered when changing between different types of tests or intervals.
