\tan\beta+\cot\beta=2

Recall that
\cot\beta=\frac1{\tan\beta}. So if
\tan\beta\\eq0, we can multiply both sides of the equation by
\tan\beta to get


\tan^2\beta+1=2\tan\beta\implies\tan^2\beta-2\tan\beta+1=0


\implies(\tan\beta-1)^2=0


\implies\tan\beta-1=0


\implies\tan\beta=1


\implies\boxed{\beta=45^\circ,225^\circ}
