Cot 1 Tan: Công thức và ví dụ đơn giản

Cot 1 tan là mối quan hệ cơ bản trong lượng giác với cot(θ) = 1/tan(θ). Bài viết giải thích chi tiết công thức, ví dụ tính toán như tanθ = 4/7 thì cotθ = 7/4, ứng dụng trong tam giác vuông và cách dùng máy tính tính cot⁻¹ qua tan⁻¹(1/x). Dễ hiểu cho học sinh.
