derivative of

2 4 - y

- \frac{1}{4 - y}

Solution steps

\frac{d}{d y} (2 4 - y)

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d y} (4 - y)

Apply the chain rule:

\frac{1}{2 4 - y} \frac{d}{d y} (4 - y)

= \frac{1}{2 4 - y} \frac{d}{d y} (4 - y)

\frac{d}{d y} (4 - y) = - 1

= 2 \cdot \frac{1}{2 4 - y} (- 1)

Simplify

2 \cdot \frac{1}{2 4 - y} (- 1) : - \frac{1}{4 - y}

= - \frac{1}{4 - y}

\int \frac{1}{x ^{2} - a ^{2}} d x

cos (x + y)

\int \frac{t}{t - 1} d t

\frac{d}{d x} (csc (5 x))

y = 3 lo g_{7} (x^{2} + 1)
