Instance Desk
| Line Section | Shading Area |
|—|—|
| [1, 2], [3, 4] | The area beneath the road section from (1, 2) to (3, 4) |
| [2, 1], [4, 3] | The area above the road section from (2, 1) to (4, 3) |
| [0, 0], [1, 1] | The area to the precise of the road section from (0, 0) to (1, 1) |
Setting Up the Shade Command
To shade in a line section on Desmos, we use the shade() command. This command takes three arguments: the start line of the road section, the ending level of the road section, and the colour or sample we wish to use to shade the area. The syntax for the shade() command is:
“`
shade(start_point, end_point, color_or_pattern)
“`
Let’s break down every of those arguments in additional element:
Begin Level
The beginning level of the road section is the purpose the place the shading will start. This level will be specified utilizing both coordinates or an expression that evaluates to a degree. For instance, to specify the beginning level as the purpose (1, 2), we’d use the next code:
“`
(1, 2)
“`
Finish Level
The tip level of the road section is the purpose the place the shading will finish. Like the beginning level, the top level will be specified utilizing both coordinates or an expression that evaluates to a degree. For instance, to specify the top level as the purpose (3, 4), we’d use the next code:
“`
(3, 4)
“`
Coloration or Sample
The colour or sample argument specifies the colour or sample that will likely be used to shade the area. This argument will be specified utilizing both a shade identify or a hex code. For instance, to shade the area utilizing the colour pink, we’d use the next code:
“`
“pink”
“`
Alternatively, we will specify the shading utilizing a hex code. A hex code is a six-digit code that represents a selected shade. For instance, the hex code for blue is “#0000FF”. To shade the area utilizing the colour blue, we’d use the next code:
“`
“#0000FF”
“`
We are able to additionally use a sample to shade the area. Patterns are created utilizing a mixture of colours and shapes. To create a sample, we use the sample() command. The syntax for the sample() command is:
“`
sample(pattern_type, color_1, color_2, …)
“`
The next desk lists the completely different sample varieties which are obtainable in Desmos:
| Sample Kind | Description |
|---|---|
| stripes | Creates a sample of stripes |
| checks | Creates a sample of checks |

| Boundary | Situation |
|---|---|
| Left | 2*x + 1 = 5 |
| Proper | 2*x + 1 = 13 |
Utilizing the Fill Command
This command enables you to fill the world between two features. You should utilize it to create a shaded space beneath your line section. The syntax for the Fill command is:
“`
Fill(Function1, Function2, LeftBound, RightBound)
“`
Operate 1 and Function2 outline the higher and decrease bounds of the world you wish to fill. LeftBound and RightBound outline the horizontal vary of your line section.
To create a easy shaded space beneath your line section, you should utilize the next syntax:
“`
Fill(Section(x_1, y_1, x_2, y_2), x_1, x_2)
“`
This can fill the world between the x-axis and your line section. You should utilize different features rather than Section to create extra complicated shaded areas.
The default shade for crammed areas is blue. You possibly can change the colour utilizing the colour() perform. The syntax for the colour() perform is:
“`
shade(r, g, b)
“`
