Question

Determine the derivative of $p = \cos (\frac{2 x}{\sqrt{2 x + 1}})$ .

Accepted Answer

$p^{'} = - \frac{2 (x + 1)}{(2 x + 1) \sqrt{2 x + 1}} \sin (\frac{2 x}{\sqrt{2 x + 1}})$

Answer

$p^{'} = - \frac{2 (x + 1)}{(2 x + 1) \sqrt{2 x + 1}} \sin (\frac{2 x}{\sqrt{2 x + 1}})$

Answer

$p^{'} = - \frac{2 (x + 1)}{(2 x + 1) \sqrt{2 x + 1}} \sin (\frac{2 x}{\sqrt{2 x + 1}})$

Answer

$p^{'} = - \frac{2 (x + 1)}{(2 x + 1) \sqrt{2 x + 1}} \sin (\frac{2 x}{\sqrt{2 x + 1}})$

Determine the derivative of p=cos(2x2x+1)p=\cos\left(\frac{2x}{\sqrt{2x+1}}\right).
