derivative of

cos (2 x + 3)

- sin (2 x + 3) \cdot 2

Solution steps

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

Apply the chain rule:

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

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

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

= - sin (2 x + 3) \cdot 2

(\frac{x}{3})^{2}

6 cos (x) + sin^{2} (x)

\frac{d}{d a} (cos^{4} (a) - sin^{4} (a) + 1)

ln (sin^{2} (e^{x}))

y = sin (\frac{x}{2})
