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

Solution

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

Solution

27 sin (3 x)

Solution steps

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

\frac{d}{d x} (cos (3 x)) = - sin (3 x) \cdot 3

= \frac{d ^{2}}{d x ^{2}} (- sin (3 x) \cdot 3)

\frac{d}{d x} (- sin (3 x) \cdot 3) = - 9 cos (3 x)

= \frac{d}{d x} (- 9 cos (3 x))

\frac{d}{d x} (- 9 cos (3 x)) = 27 sin (3 x)

= 27 sin (3 x)
