![\frac{d}{dx} [sin(u)] = cos(u) \cdot u'](/tpl/images/1008/8139/dae39.png)
Product Rule: ![\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)](/tpl/images/1008/8139/1493b.png)
Subtract ycos(x) on both sides: 
Subtract xy'cos(y) on both sides: 
Factor out y': ![y'[sin(x) - xcos(y)] = sin(y) - ycos(x)](/tpl/images/1008/8139/16ed7.png)
Isolate y':
