cosθ=－2/1のときのθは求めれたのですが、cosθ=－1はなぜ、解くとθ=πになっているのか、θ=3/2π,π,3/4πはどのようにして求めていますか？

26300 <2πのとき, 次の方程式を解け。 * (1) 2cos²0+3sin0=0 (2) 2sin²0-3 cos 0-3=0

236の(1)で、2枚目の写真の解説の線を引いているところ(2sin〜6/11π）から分からないです。 なぜ2sinθ＋1=0だけを使っていて(sin－2)を使ってないのか、sinθ=－2/1が出て、どのようにしてθ=6/7π,6/11πが出てきたのかが知りたいです。

2のとき、次の方程式を解け。 *(1) 2cos²0+3sin0=0 (2) 2sin²0-3 cos 0-3=0 2630

教えて欲しいです！
