My calc professor always used to use the symbol ##:=## when defining a quantity.
For example, say we want to evaluate the integral ## \int x \sqrt{1+x^2} dx ##. So we might say, "Let ##u:=1+x^2 ##" and then continue to easily evaluate the integral.
I haven't seen this anywhere else and I'm wondering if this is standard notation.
