derivative of sqrt(1+2x^2)

Solution

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

Solution

\frac{2 x}{1 + 2 x ^{2}}

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (1 + 2 x^{2}) = 4 x

= \frac{1}{2 1 + 2 x ^{2}} \cdot 4 x

Simplify

\frac{1}{2 1 + 2 x ^{2}} \cdot 4 x : \frac{2 x}{1 + 2 x ^{2}}

= \frac{2 x}{1 + 2 x ^{2}}
