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

sin (2 (a - x))

Solution steps

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

Apply the chain rule:

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

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

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

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

Use the Double Angle identity:

2 sin (x) cos (x) = sin (2 x)

= sin (2 (a - x))

f (x) = \frac{x + x ^{3}}{x}

y^{^{''}} - 7 y^{^{'}} + 12 y = 0, y (0) = 1, y^{^{'}} (0) = - 2

x \to 4 lim (\frac{5}{x - 3})

y = \frac{x - 2}{x - 2}

\frac{\partial}{\partial x} (2 e^{5 x y})
