GlyphIndexDefined change
∆t = t₂ − t₁ = 8 s − 3 s = 5 s
This note defines the elapsed-time increment explicitly.
Increment sign
The increment sign ∆ can label a change, such as ∆t. It looks like Greek capital delta Δ but has a different code point.

The increment sign ∆ can label a change, such as ∆t. It looks like Greek capital delta Δ but has a different code point.
How to use it
If an existing formula uses Greek delta, preserve that character. When choosing an increment notation for a new note, define it as a difference before using it.
Examples
Two encodings
∆ (U+2206) and Δ (U+0394)
The comparison is about encoded characters, not a promised visible difference.
