derivative of

f (x) = 1 - 2 x

- \frac{1}{1 - 2 x}

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

\frac{1}{2 1 - 2 x} (- 2) : - \frac{1}{1 - 2 x}

= - \frac{1}{1 - 2 x}

\frac{x ^{4}}{4}

(y - 2 x - 1) d x + (x + y - 4) d y = 0

n \to \infty lim (4^{n})

x = - 2, x = 3, y = 2 x^{2} + 10, y = 0

f (x) = 9 e^{x} cos (x), at x = 0
