(d^3)/(dx^3)(cos(x))

Solution

\frac{d ^{3}}{d x ^{3}} (cos (x))

Solution

sin (x)

Solution steps

\frac{d ^{3}}{d x ^{3}} (cos (x))

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

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

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

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

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

= sin (x)
