if \(\cos(x)=\cot(x)\) then
\[\cos(x)=\frac{\cos(x)}{\sin(x)}\] and so
\[\cos(x)\sin(x)=\cos(x)\]
\[\cos(x)\sin(x)-\cos(x)=0\]
\[\cos(x)(\sin(x)-1)=0\]
\[cos(x)=0\implies x=\frac{\pi}{2}\] \[\sin(x)=1\implies x=\frac{\pi}{2}\]

cotx=cosx/sinx;sinx*cotx=(sinx)(cosx/sinx) cancel out sinx u left with cosx=1
