b.

\(\Leftrightarrow\dfrac{1}{2}cosx-\dfrac{\sqrt{3}}{2}sinx=-\dfrac{1}{2}\)

\(\Leftrightarrow cos\left(x+\dfrac{\pi}{3}\right)=-\dfrac{1}{2}\)

\(\Leftrightarrow\left[{}\begin{matrix}x+\dfrac{\pi}{3}=\dfrac{2\pi}{3}+k2\pi\\x+\dfrac{\pi}{3}=-\dfrac{2\pi}{3}+k2\pi\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{\pi}{3}+k2\pi\\x=-\pi+k2\pi\end{matrix}\right.\)

c.

\(\Leftrightarrow\dfrac{3}{5}sinx-\dfrac{4}{5}cosx=1\)

Đặt \(\dfrac{3}{5}=cosa\) với \(a\in\left(0;\dfrac{\pi}{2}\right)\Rightarrow\dfrac{4}{5}=sina\)

Pt trở thành:

\(sinx.cosa-cosx.sina=1\)

\(\Leftrightarrow sin\left(x-a\right)=1\)

\(\Leftrightarrow x-a=\dfrac{\pi}{2}+k2\pi\)

\(\Leftrightarrow x=a+\dfrac{\pi}{2}+k2\pi\)
