Q & A
What is Desmos and how do you start using it?
-Desmos is a graphing calculator that allows you to type in mathematical equations and visualize them. To start using it, you type in equations or calculations on the left-hand side of the interface.
How can you create an equation like y = x + 2 on Desmos?
-You can create an equation like y = x + 2 by typing it directly into the math editor on the left-hand side of the Desmos interface.
What is the purpose of the graphing area on the right-hand side of Desmos?
-The graphing area on the right-hand side of Desmos is where you can visualize the equations you've entered. It allows you to see the graph of the equation and interact with it.
How can you adjust the graph settings on Desmos?
-You can adjust the graph settings by clicking on the wrench icon, which opens a menu where you can change the range and domain of the X and Y axes, as well as the grid step.
What are the zoom options available in Desmos?
-In Desmos, you can zoom in and out using the zoom buttons or by using your mouse wheel if you have one. Alternatively, you can use pinch-to-zoom gestures on a touchpad or touchscreen.
How do you remove an equation or calculation from the graph?
-To remove an equation or calculation from the graph, you can click on the 'X' next to the equation in the math editor.
What features can you change for a graph line using the gear icon?
-Using the gear icon, you can change the color, line style (solid or dashed), and thickness of the graph line.
How can you display a table of X and Y pairs for a line on Desmos?
-You can display a table of X and Y pairs by clicking on 'Create table' which will show the coordinates for each point on the line.
What is the significance of the intersection points labeled on the graph?
-The intersection points labeled on the graph are where two graphs intersect. These points are significant for discussions about where two functions meet.
How do you calculate the square root of a number on Desmos?
-You can calculate the square root of a number by typing 'sqrt' followed by the number, or by using the square root button on the keypad. Alternatively, you can use the abbreviation 'sq rt' followed by the number.
What is a quick way to input fractions on Desmos?
-A quick way to input fractions on Desmos is by using the forward slash '/' key. After typing the numerator, press '/' and then type the denominator.
