Giải phương trình tan3x = tanx và liên hệ với phân tích dữ liệu.

1. x + 2x = 3x 2. \tan(A + B) = \dfrac{\tan(A) + \tan(B)}{1 - \tan(A)\tan(B)} 3. \displaystyle \int The first part is relatively simple. If we write tan(3x) as tan(2x+x) we can use addition formulae to give: tan(2x+x)= (tan(2x)+tan(x))/(1-tan(2x)tan(x)) Sep 5, 2024 ... The number of solutions is 7. Ask your next question. Or.
