How to say "exponential" in Japanese
Choosing the right word
- 指数的しすうてきna-adjectiveCovers the mathematical sense of 'exponential': growth or increase that multiplies by a fixed factor at each step. The shorter and more general of the two adjectives, though relatively uncommon.
- 指数関数的しすうかんすうてきna-adjectiveThe same mathematical sense, but it names the exponential function itself, making the technical basis explicit. Largely interchangeable with the shorter adjective; also relatively uncommon.
Both relatively uncommon adjectives mean 'exponential' in the mathematical sense of growth by repeated multiplication; 指数的 is the shorter, more general form, while 指数関数的 is fuller, explicitly naming the exponential function.
