There is no particular symbol for "no change". However, if you know the quantity that has not changed, for example represented by H, you could write "ΔH = 0".
Δ is the accepted symbol for "change in/of .." so if the change equals zero then there is no change.

Mr. Euler
As the ratio of two lengths, the radian is a "pure number" that needs no unit symbol, and in mathematical writing the symbol "rad" is almost always omitted. In the absence of any symbol radians are assumed, and when degrees are meant the symbol ° is used.
Divide the change by the initial number to get a fraction and multiply by 100% to get a percent. The percent you get will describe the change in area in the mathematical language of numbers.
It was popularized by Leonhard Euler, when he adopted the symbol in 1737. By this time, Euler was already a fairly prominent mathematician, serving as head of the mathematics department at the Academy at St. Petersburg. As far as modern historians know, the symbol was first used for that purpose in print in 1706, by Welsh mathematician called William Jones. Prior to that, the symbol for pi was used for the circumference of a circle, not for the (constant) ratio of that circumference to the circle's diameter.
It is called delta, the capital Greek letter, Δ, and it symbolizes change in.
I think its this symbol
What mathematical symbol? Different symbols were invented in different times and places.
"why" is not a mathematical symbol.
There is no standard symbol for subring
It's a mathematical metaphor.

The mathematical symbol for "undefined" is the infinity symbol.
