(d^3)/(dx^3)(sin(7x))

Solution

\frac{d ^{3}}{d x ^{3}} (sin (7 x))

Solution

- 343 cos (7 x)

Solution steps

\frac{d ^{3}}{d x ^{3}} (sin (7 x))

\frac{d}{d x} (sin (7 x)) = cos (7 x) \cdot 7

= \frac{d ^{2}}{d x ^{2}} (cos (7 x) \cdot 7)

\frac{d}{d x} (cos (7 x) \cdot 7) = - 49 sin (7 x)

= \frac{d}{d x} (- 49 sin (7 x))

\frac{d}{d x} (- 49 sin (7 x)) = - 343 cos (7 x)

= - 343 cos (7 x)
