Verbum Paper - Share the math!
#
Verbum Paper is a software that is intended to be used to facilitate the sharing of formulas, equations, and things involving mathematics.
Through it you can write your file using CSS, HTML and Javascript code. You can import external libraries written in Javascript, such as for building graphics, or for something in particular.
Via Verbum Paper you can insert graphics for functions (eg 2nd degree functions). You can also insert LaTex code mixed in with your HTML code.
You can also copy your math expressions to Clipboard. This way you can easily share your math equations with your friends :smiley:

Below is a simple example, where we create a graph of a function, using the FunctionPlot library. And we make use of LaTex commands to display an equation.
```html
Quadratic function
Defination: quadratic function is a function
f: ℝ → ℝ, x ∈ ℝ,
that can be described by an equation of the form
f(x) = ax² + bx + c, where a ≠ 0.
Graph of a quadratic function
functionPlot({
target: "#function",
width: 400,
height: 200,
yAxis: { domain: [-1, 9] },
grid: true,
data: [ {
fn: "x^2"
}]
});
Root of the quadratic function:
\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
```
The view will look like this:
:white_square_button: LaTex code
---
To insert LaTex code, you must follow the MathLive specification: https://cortexjs.io/mathlive/reference/commands/
Example to include an equation:
```latex
\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
```
This code produces this view:

### Function Plot - A 2d function plotter powered by D3
To create graphs of quadratic functions, the Function Plot library is used.
Exemple:
```html
```
```javascript
functionPlot({
target: "#function",
width: 400,
height: 200,
yAxis: { domain: [-1, 9] },
grid: true,
data: [ {
fn: "x^2"
}]
});
```
The code above will produce this view:
:bar_chart: General Graphics
---
### D3 - Data-Driven Documents
To produce graphics for different applications, it is recommended to use the D3 library.
Below is an example using the D3 library:
```html
```
```javascript
// Format JSON data.
var json_data = `
[
{ "date":"2013-04-28", "value":"135.98" },
{ "date":"2013-04-29", "value":"147.49" }
]
`;
// set the dimensions and margins of the graph
const margin = {top: 10, right: 30, bottom: 30, left: 60},
width = 460 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;
// append the svg object to the body of the page
const svg = d3.select("#d3-graph")
.append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", `translate(${margin.left},${margin.top})`);
json_data = JSON.parse(json_data);
for (var a=0; a it is a date format
const x = d3.scaleTime()
.domain(d3.extent(json_data, function(d) { return d.date; }))
.range([ 0, width ]);
svg.append("g")
.attr("transform", `translate(0, ${height})`)
.call(d3.axisBottom(x));
// Add Y axis
const y = d3.scaleLinear()
.domain([0, d3.max(json_data, function(d) { return +d.value; })])
.range([ height, 0 ]);
svg.append("g")
.call(d3.axisLeft(y));
// Add the line
svg.append("path")
.datum(json_data)
.attr("fill", "none")
.attr("stroke", "steelblue")
.attr("stroke-width", 1.5)
.attr("d", d3.line()
.x(function(d) { return x(d.date) })
.y(function(d) { return y(d.value) })
)
```
The code above will produce this view:
### Chart.js
You can also use the Chart.js library to create charts.
Exemple:
```html
```
```javascript
var xValues = [50,60,70,80,90,100,110,120,130,140,150];
var yValues = [7, 8, 8, 9, 9, 9, 10, 11, 14, 14, 15 ];
new Chart("chart-example", {
type: "line",
data: {
labels: xValues,
datasets: [{
fill: false,
lineTension: 0,
backgroundColor: "rgba(0,0,255,1.0)",
borderColor: "rgba(0,0,255,0.1)",
data: yValues
}]
},
options: {
legend: {display: false},
scales: {
yAxes: [{ticks: {min: 6, max:16}}],
}
}
});
```
Graph view:
:computer: Highlight code
---
To highlight code, it is recommended to use the Highlight.js library.
```html
functionPlot({
target: "#function",
width: 400,
height: 200,
yAxis: { domain: [-1, 9] },
grid: true,
data: [ {
fn: "x^2"
}]
});
```
