안녕하세요. 몇 군데 보내야 할 글을 다 쓰고 난 뒤 월급도둑질 중인 세상의빛입니다. 월도짓 중 떠오른 문제가 안 풀리네요. ㅎㅎ 0과 1 사이의 실수인 a에서 a를 밑으로 하는 로그함수와 지수함수의 함수값이 같을 때 즉 logaX = a^X 인 식이 있을 때 X를 어떻게 구할 수 있을까요.. 그래프를 그려보면 만나는 점이 있기는 한데 그 값을 구하려니 제 실력으로는 풀기가 어렵네요. PS. 전달이 제대로 안 된 부분이 있어서 수정했습니다. ㅠ Warning: Use of undefined constant no - assumed 'no' (this will throw an Error in a future version of PHP) in /home/redtea/html/a_skin/bbsd/view.php on line 135 Warning: Use of undefined constant no - assumed 'no' (this will throw an Error in a future version of PHP) in /home/redtea/html/a_skin/bbsd/view.php on line 148 Warning: Use of undefined constant vote - assumed 'vote' (this will throw an Error in a future version of PHP) in /home/redtea/html/a_skin/bbsd/view.php on line 163 0 |
