LaTeX Equation Formatting Discrepancy in Copilot for PC vs. Mobile

Question

Report Date: April 8, 2025
Device: Windows 10.0 PC
Issue Type: Formatting/Rendering Issue

Issue Summary

The Copilot AI interface on Windows 10 PC fails to properly render mathematical equations formatted in LaTeX notation, while the mobile version displays them correctly. When equations enclosed in $$ (double dollar signs) are entered, the PC version does not format them as mathematical expressions, whereas the mobile app presents them in proper notation.

Steps to Reproduce

1. Open Copilot on a Windows 10 PC.
2. Request a mathematical equation formatted in LaTeX. Example:

   $$\text{ROIC} = \frac{\text{NOPAT}}{\text{Debt} + \text{Equity} - \text{Non-Operating Assets}}$$
   $$\text{ROC} = \frac{\text{Operating Income}}{\text{Debt} + \text{Equity}}$$

1. Observe that on Copilot for PC, the formulas appear incorrectly as plain text or misformatted equations.
2. Check the same request on Copilot Mobile, and note that the equations are properly displayed.

Expected Behavior

Copilot should consistently support LaTeX rendering across all platforms. Equations enclosed in $$ should be formatted as proper mathematical expressions, rather than raw text. Copilot PC should match the rendering behavior of Copilot Mobile, ensuring a unified user experience.

Actual Behavior

On Copilot for PC, equations formatted in LaTeX appear incorrectly or as unformatted text. On Copilot Mobile, the same equations are properly rendered.

Impact

Users working with financial calculations and technical equations face readability issues on Copilot PC. Inconsistencies between platforms disrupt the user experience, requiring manual formatting workarounds. Key financial analysis, mathematical notation, and academic use cases are affected due to improper rendering.

Suggested Fix

• Ensure Copilot for PC supports LaTeX rendering, aligning it with the mobile version.
• Investigate whether the markdown or rendering engines require updates to process equations correctly.
• Implement consistent equation formatting across all Copilot platforms.
