(d^3)/(dx^3)(cos(2x))

Solution

\frac{d ^{3}}{d x ^{3}} (cos (2 x))

Solution

8 sin (2 x)

Solution steps

\frac{d ^{3}}{d x ^{3}} (cos (2 x))

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

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

\frac{d}{d x} (- sin (2 x) \cdot 2) = - 4 cos (2 x)

= \frac{d}{d x} (- 4 cos (2 x))

\frac{d}{d x} (- 4 cos (2 x)) = 8 sin (2 x)

= 8 sin (2 x)
