derivative

sec^{2} (\frac{x}{2}) \frac{1}{2}

Solution steps

\frac{d}{d x} (tan (\frac{x}{2}))

Apply the chain rule:

sec^{2} (\frac{x}{2}) \frac{d}{d x} (\frac{x}{2})

= sec^{2} (\frac{x}{2}) \frac{d}{d x} (\frac{x}{2})

\frac{d}{d x} (\frac{x}{2}) = \frac{1}{2}

= sec^{2} (\frac{x}{2}) \frac{1}{2}
