Phương trình đường tròn \(\left(x-a\right)^2+\left(y-b\right)^2=R^2\) với tâm \(I=\left(a;b\right)\), bán kính \(R\)

\(\Rightarrow\) Tâm đường tròn \(\left(x-1\right)^2+\left(y+2\right)^2=4\) có tọa độ \(\left(1;-2\right)\)

Kết luận: Tâm đường tròn có tọa độ \(\left(1;-2\right)\).

Cos đối, sin bù, phụ chéo, khác \(\pi\) tan, kém \(\dfrac{\pi}{2}\) chéo sin

\(sin\left(x+\dfrac{\pi}{2}\right)=sin\left(\dfrac{\pi}{2}-\left(-x\right)\right)=cos\left(-x\right)=cosx\)

Kết luận: \(sin\left(x+\dfrac{\pi}{2}\right)=cosx\)

\(\dfrac{1-2x}{x+1}\ge-1\)

\(\Leftrightarrow\dfrac{1-2x}{x+1}+1\ge0\)

\(\Leftrightarrow\dfrac{2-x}{x+1}\ge0\)

\(\Leftrightarrow\left[{}\begin{matrix}\left\{{}\begin{matrix}2-x\ge0\\x+1>0\end{matrix}\right.\\\left\{{}\begin{matrix}2-x\le0\\x+1< 0\end{matrix}\right.\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}-1< x\le2\\\left\{{}\begin{matrix}x\ge2\\x< -1\end{matrix}\right.\left(vn\right)\end{matrix}\right.\)

\(\Leftrightarrow-1< x\le2\)

\(\Leftrightarrow x\in(-1;2]\)

Kết luận: \(x\in(-1;2]\)
