Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to find the derivative of [tex]-ln(-\Theta)[/tex] with respect to [tex]\Theta[/tex]

The answer's [tex]-\frac{1}{\Theta}[/tex]

I'm not sure why though. Here's my working.

[tex]\frac{d}{d\Theta} -ln(-\Theta)[/tex]

[tex] = \frac{d}{d\Theta} ln(-\frac{1}{\Theta})[/tex]

[tex] = -\Theta[/tex]

Can anyone explain where I'm going wrong? Thanks.
