\frac{d}{d a} (cos (a) sin (a))

cos (2 a)

Solution steps

\frac{d}{d a} (cos (a) sin (a))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = cos (a), g = sin (a)

= \frac{d}{d a} (cos (a)) sin (a) + \frac{d}{d a} (sin (a)) cos (a)

\frac{d}{d a} (cos (a)) = - sin (a)

\frac{d}{d a} (sin (a)) = cos (a)

= (- sin (a)) sin (a) + cos (a) cos (a)

Simplify

(- sin (a)) sin (a) + cos (a) cos (a) : cos (2 a)

= cos (2 a)

\frac{d}{d x} (- 5 x y (x + y) + 6)

\frac{\partial}{\partial x} (\frac{x}{a})

\int - \frac{25}{x ^{26}} d x

t^{2} \cdot y^{^{'}} + t \cdot y = 7

\int x^{3} cos (x^{4}) d x
