Sử dụng tan x/2 trong mô hình hóa ngôn ngữ? tan x/2 trong các bài toán về toán học ứng dụng trong khảo cổ học?

sin 2x = 2 sin x cos x; cos 2x = cos2 x - sin2 x (or) = 1 - 2 sin2x (or) = 2 cos2x - 1; tan 2x = 2 tan x / (1 - tan2x). If we replace x with A/2 on both sides ... Apr 19, 2023 ... We find the derivative of tanx^2 with the chain rule, tan^2x with the chain rule, and tan2x also with the chain rule.
