使用する際の注意点

Regarding the use of sense 5 (“to come near to (someone または something) in place, time, character, or value”) in discussing convergence in mathematical analysis, modern rigorous formulations avoid using the words approach and converge. However, the terms are used informally when rigour is not required.
