ExamGhost for DeltaMath is a Manifest V3 Chrome extension engineered for DeltaMath Homework & Timed Assessments (deltamath.com/app/student/*). Double-click any .problem-div prompt one by one to extract MathQuill/KaTeX equations without copying, or press Alt+S to get exact $(x, y)$ plotting coordinates, asymptotes, and vertex points for DeltaMath interactive graphs.
Double-clicking Question 1 on DeltaMath triggers an inline solve, selects the verified option, and opens the Right-Side Answer Banner.
Built for deltamath.com MathQuill, Simplest Radical Form, and Canvas graphs.
DeltaMath Student App Architecture
DeltaMath prevents standard text copying on many problem types, renders equations inside nested KaTeX / MathQuill spans, and grades interactive graphing questions by checking exact vertex, asymptote, and intercept coordinates on an HTML5 <canvas>. ExamGhost extracts clean LaTeX on double-click and outputs exact plotting coordinates in Explain Mode.
When DeltaMath asks you to “Plot five points on the parabola: the vertex, two points to the left, and two points to the right” or drag asymptotes on a rational function, switch to Explain Mode (Alt+3) and double-click the prompt—ExamGhost lists the exact $(x, y)$ integer/half-integer points and asymptote lines to click on the grid.
Highlighting and copying a DeltaMath problem either gets blocked by user-select: none CSS or copies broken MathML duplicates. Double-clicking the .problem-div with ExamGhost parses the underlying math tree directly with zero clipboard interaction.
For geometry congruence proofs, unit-circle terminal rays, and “determine the equation from the graph” problems, press Alt+S and drag across the DeltaMath canvas. ExamGhost reads the plotted coordinates and outputs the answer in Simplest Radical Form.
DeltaMath Technical Comparison
| DeltaMath Capability / Telemetry Vector | ExamGhost (In-Page AI) | ChatGPT Tab-Switching | Legacy Sidebar Extensions |
|---|---|---|---|
Works when DeltaMath disables text selection (user-select: none) | Yes (Double-Click DOM Parse) | Blocked (Must Re-Type Equations) | Fails on KaTeX / MathQuill Spans |
| Gives exact (x, y) points + asymptotes to plot on DeltaMath graphs | Yes (5-Point Table in Explain Mode) | Generic Formula Only | Cannot Read Canvas Grid Bounds |
| Outputs "Simplest Radical Form" & exact rational fractions | Yes (Matches DeltaMath Keypad) | Often Gives Decimal Approximations | Wrong Radical Formatting |
Reads DeltaMath <canvas> geometry & trigonometry figures | Instant Alt+S Viewport Crop | Manual Screenshot Save/Upload | Blind to HTML5 Canvas Nodes |
| Natural per-problem Time Spent in teacher dashboard logs | One-by-One Human Pacing | Long Off-Tab Idle Gaps | Injects Detectable Sidebar DOM |
