Find the 2nd Derivative y=cos(x)

second derivative

y = cos (x)

- cos (x)

Solution steps

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

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

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

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

= - cos (x)

- \frac{d}{d x} y = sinh (cosh (x))

\frac{( f ( x ) ( x + h ( x ) ) - f ( x ) )}{h ( x ) , f ( x )} = \frac{3}{( x ^{2} )}

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

- \frac{d}{d x} y = x e^{x}

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