\frac{d}{d x} (cos (x - \frac{π}{6}))

- \frac{3}{2} sin (x) + \frac{1}{2} cos (x)

Solution steps

\frac{d}{d x} (cos (x - \frac{π}{6}))

Simplify

cos (x - \frac{π}{6}) : \frac{3}{2} cos (x) + \frac{1}{2} sin (x)

= \frac{d}{d x} (\frac{3}{2} cos (x) + \frac{1}{2} sin (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (\frac{3}{2} cos (x)) + \frac{d}{d x} (\frac{1}{2} sin (x))

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

\frac{d}{d x} (\frac{1}{2} sin (x)) = \frac{1}{2} cos (x)

= - \frac{3}{2} sin (x) + \frac{1}{2} cos (x)

y^{^{'}} = y e^{x}

y = (1 - 5 x)^{6}

y = 7 x + 1, (5, 6)

x \to 0 lim ((1 + 3 x)^{\frac{4}{x}})

\frac{\partial}{\partial x} ((y - x^{2}) (2 y^{2} + x))
