The posts $X$ is homeomorphic to $X\times X$ (TIFR GS $2014$) and What can be said about topological properties of a space $X$ that is homeomorphic to $X\times X$ $?$ are (in my opinion) duplicates of each other. They contain exactly the same question (probably from the same school or from the sa...

I think that Verifying some trigonometric identities: $\frac{\csc\theta}{\cot\theta}-\frac{\cot\theta}{\csc\theta}=\tan\theta\sin\theta$ and Proving that $\frac{\csc\theta}{\cot\theta}-\frac{\cot\theta}{\csc\theta}=\tan\theta\sin\theta$ are duplicates. The post with more answers seems to be a rea...
