dealing with parametric curves
if dy/dx = dy/dt/dx/dt = sin(t)/2sin(2t)
now I need to find d^2y/dx^2 and i'm a bit stuck...

Best ResponseYou've already chosen the best response.0\[\frac{ \frac{ d }{ dt }(\frac{ \sin(t) }{ 2\sin(2t) }) }{ 2\sin(2t) }\] then I would have\[\frac{ \frac{ \cos (t) }{ 4\cos(2t)} }{ 2\sin(2t) }\] is that correct?

Best ResponseYou've already chosen the best response.2\[\frac d{dt}(\frac{\sin t}{2\sin 2t})\neq\frac{\cos t}{4\cos t}\]remember the quotient rule...

Best ResponseYou've already chosen the best response.2you may do well to simplify first\[\frac{\sin t}{2\sin(2t)}=\frac{\sin t}{4\sin t\cos t}=\frac1{4\cos t}=\frac14\sec t\]
