(d^4)/(dx^4)(cos(2x))

Solution

\frac{d ^{4}}{d x ^{4}} (cos (2 x))

Solution

16 cos (2 x)

Solution steps

\frac{d ^{4}}{d x ^{4}} (cos (2 x))

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

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

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

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

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

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

\frac{d}{d x} (8 sin (2 x)) = 16 cos (2 x)

= 16 cos (2 x)
