\frac{d}{d x} (3 sin (x) - 2 cos (x))

3 cos (x) + 2 sin (x)

Solution steps

\frac{d}{d x} (3 sin (x) - 2 cos (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (3 sin (x)) = 3 cos (x)

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

= 3 cos (x) - (- 2 sin (x))

Simplify

= 3 cos (x) + 2 sin (x)

x \to 3 lim ((4 x + 5) (6 x - 7))

\int x 1 + y^{3} d y

\int (x^{8} - 4 x^{3} - x) d x

f (x) = \frac{8 + x}{1 - 8 x}

t \to π lim (cos (\frac{t}{3}))
