Interface EQN_Root

Equation root

Surround an equation phrase with a radical symbol EQN_RadicalSymbol and add a custom root if needed

Options can be an object, or an array in the property order below.

To test examples, append them to the boilerplate

Example

// Simple
figure.add({
  name: 'eqn',
  make: 'equation',
  forms: {
    1: { root: ['radical', 'a'] },
  },
});
figure.elements._eqn.showForm('1');

Example

// Example showing object and array root definitions, and custom roots
figure.add({
  name: 'eqn',
  make: 'equation',
  elements: {
    r: { symbol: 'radical' },
    plus: '  +  ',
  },
  formDefaults: { alignment: { fixTo: 'd' } },
  forms: {
    // Root object form
    1: {
      root: {
        symbol: 'r',
        content: ['a', 'plus', 'd'],
      },
    },
    // Root array form
    2: { root: ['r', 'd'] },
    // Cube root
    3: { root: { content: 'd', symbol: 'r', root: '_3' } },
  },
  formSeries: ['1', '2', '3'],
});
const eqn = figure.elements._eqn;
eqn.onClick = () => eqn.nextForm();
eqn.setTouchable();
eqn.showForm('1');

Example

// Create equation object then add to figure
const eqn = figure.collections.equation({
  elements: {
    r: { symbol: 'radical' },
    plus: '  +  ',
  },
  formDefaults: {
    alignment: { fixTo: 'd' },
  },
  forms: {
    1: {
      root: {
        symbol: 'r',
        content: ['a', 'plus', 'd'],
      },
    },
    2: { root: ['r', 'd'] },
    3: { root: { content: 'd', symbol: 'r', root: '_3' } },
  },
  formSeries: ['1', '2', '3'],
});
figure.add('eqn', eqn);
eqn.onClick = () => eqn.nextForm();
eqn.setTouchable();
eqn.showForm('1');
