I'm not getting this. Can someone show me how they got from this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] - T cos ( \theta ) + (T + \Delta T ) cos ( \theta + \Delta \theta ) =0 [/tex]

to below by dividing by [tex] \Delta x [/tex]

[tex] \frac { d (T cos\theta)}{dx} = 0 [/tex]

Im just not getting it for some reason.... The first term would be Tcos(theta)/ dx, which should turn into 1/0, which blows up to infinity?

Thank you,

Cyrus
