(d^2)/(dt^2)(cos^2(t))

Solution

\frac{d ^{2}}{d t ^{2}} (cos^{2} (t))

Solution

- cos (2 t) \cdot 2

Solution steps

\frac{d ^{2}}{d t ^{2}} (cos^{2} (t))

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

= \frac{d}{d t} (- sin (2 t))

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

= - cos (2 t) \cdot 2
