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 is called delta, the capital Greek letter, Δ, and it symbolizes change in.

What mathematical symbol? Different symbols were invented in different times and places.

It's a mathematical metaphor.
