Các bạn chỉ mình ạ! Bài 1: Sin, cos, tan, cot là tỉ số lượng giác đúng không ạ. + Ví dụ $sin60^o$, $sin\frac{1}{2}$ Thì hai cái này khác nhau như thế nào ạ? Có phải là tìm tỉ số lượng giác của góc 60 độ là bao nhiêu. Tìm số đo góc biết tỉ số lượng giác là 1/2 ạ. + $sin60^o$, $sin\frac{1}{2}$. Mình chưa hiểu rõ như nào là tỉ số lượng giác, có phải số thì mới là tỉ số lượng giác không ạ, còn góc thì không phải. Cùng có sin khác nhau ở số đo góc và số Bài 2: Khi góc $\alpha $ tăng từ 0 độ đến 90 độ thì: $sin\alpha $ và $tan\alpha $ tăng $cos\alpha $ và $cot\alpha $ giảm. + góc $\alpha $ Có lớn hơn 90 độ không ạ? còn góc $\beta $ thì sao ạ. + Góc $\beta $ và $\alpha $ có giốn nhau không ạ
