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
