jamierox4ev3r · Answer

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

zzr0ck3r · Answer

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

hmm not sure this is true...

loser66 · Answer

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

jamierox4ev3r · Answer

really? that is definitely not what my paper says

jamierox4ev3r · Answer

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

jamierox4ev3r · Answer

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.
