derivative of

arctan (2 y)

\frac{2}{4 y ^{2} + 1}

Solution steps

\frac{d}{d y} (arctan (2 y))

Apply the chain rule:

\frac{1}{( 2 y ) ^{2} + 1} \frac{d}{d y} (2 y)

= \frac{1}{( 2 y ) ^{2} + 1} \frac{d}{d y} (2 y)

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

= \frac{1}{( 2 y ) ^{2} + 1} \cdot 2

Simplify

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

= \frac{2}{4 y ^{2} + 1}

\int 3 x^{3} e^{2 x} d x

\frac{\partial}{\partial x} (arctan (x - 2 y))

\int x - x d x

\frac{2}{x}

y^{^{''}} - a y = 0
