(d^2)/(dx^2)(2cos(x/2))

Solution

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

Solution

- cos (\frac{x}{2}) \frac{1}{2}

Solution steps

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

\frac{d}{d x} (2 cos (\frac{x}{2})) = - sin (\frac{x}{2})

= \frac{d}{d x} (- sin (\frac{x}{2}))

\frac{d}{d x} (- sin (\frac{x}{2})) = - cos (\frac{x}{2}) \frac{1}{2}

= - cos (\frac{x}{2}) \frac{1}{2}

y^{^{'}} + y (\frac{3}{x} + \frac{x}{2}) = 0
