\frac{d}{d x} (cos^{2} (2 x - 1))

- 4 cos (2 x - 1) sin (2 x - 1)

Solution steps

\frac{d}{d x} (cos^{2} (2 x - 1))

Apply the chain rule:

2 cos (2 x - 1) \frac{d}{d x} (cos (2 x - 1))

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

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

= 2 cos (2 x - 1) (- sin (2 x - 1) \cdot 2)

Simplify

= - 4 cos (2 x - 1) sin (2 x - 1)

f (t) = t^{5}

x \to 1 lim (\frac{x ^{2} - 1}{x})

x + y^{2} = 56, x + y = 0

\frac{d}{d x} (\frac{2 x ^{4}}{b ^{2} - x ^{2}})

\int (2 - 3 x)^{3} d x
