    Verify that: \(\Large \frac{(\sin \theta)(\sin \theta)-(1-\cos \theta)(\cos \theta)}{\sin ^{2}\theta}=\csc \theta - \cot \theta\)

    Hint: \[\sin^2(\theta)-\cos(\theta)+\cos^2(\theta)=\sin^2(\theta)+\cos^2(\theta)-\cos(\theta)=1-\cos(\theta)\]

    That shows they are not equal, right? 2 functions "meet" to each other at some specific points.
