1. Jamierox4ev3r

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

2. zzr0ck3r

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

3. zzr0ck3r

hmm not sure this is true...

4. Loser66

check the right hand side, please. It should be (csc (1-cot)

5. Jamierox4ev3r

really? that is definitely not what my paper says

6. Jamierox4ev3r

it could be a typo, I should ask my instructor tomorrow

7. Jamierox4ev3r

hmm... I guess I'll close this for now, I'll get back with you guys on this later

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