- Foldable left panel (user profile) and right panel (task details) - Clicking a task in the list or graph node selects it and shows details - Both views (task list + graph) always mounted via absolute inset-0 for correct canvas dimensions; tabs toggle visibility with opacity - Graph node selection animation: other nodes repel outward (charge -600), then selected node smoothly slides to center (500ms cubic ease-out), then charge restores to -120 and graph stabilizes - Graph re-fits on tab switch and panel resize via ResizeObserver - Fix UUID string IDs throughout (backend returns UUIDs, not integers) - Add TaskDetailPanel, UserPanel components - Add CLAUDE.md project documentation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Given the ratio a : b : c = 2 : 3 : 4
|
|
What is c, given a = 40?
|
|
|
|
A general ratio chain is a_1 : a_2 : a_3 : ... : a_n = r_1 : r2 : r_3 : ... : r_n.
|
|
Now each term can be expressed as a_i = r_i * x for some unknown proportional constant x.
|
|
If a_k is known it follows that x = a_k / r_k. Substituting x into the first equation yields
|
|
a_i = r_i / r_k * a_k.
|
|
|
|
Given an array r and a given value a_k, the following function calculates all a_i:
|
|
*/
|
|
|
|
function calculateRatios(r, a_k, k) {
|
|
const x = Fraction(a_k).div(r[k]);
|
|
return r.map(r_i => x.mul(r_i));
|
|
}
|
|
|
|
// Example usage:
|
|
const r = [2, 3, 4]; // Ratio array representing a : b : c = 2 : 3 : 4
|
|
const a_k = 40; // Given value of a (corresponding to r[0])
|
|
const k = 0; // Index of the known value (a corresponds to r[0])
|
|
|
|
const result = calculateRatios(r, a_k, k);
|
|
console.log(result); // Output: [40, 60, 80]
