\frac{d}{d x} (arctan (3 x^{2} - 1))

\frac{1}{x 3 x ^{2} - 1}

Solution steps

\frac{d}{d x} (arctan (3 x^{2} - 1))

Apply the chain rule:

\frac{1}{( 3 x ^{2} - 1 ) ^{2} + 1} \frac{d}{d x} (3 x^{2} - 1)

= \frac{1}{( 3 x ^{2} - 1 ) ^{2} + 1} \frac{d}{d x} (3 x^{2} - 1)

\frac{d}{d x} (3 x^{2} - 1) = \frac{3 x}{3 x ^{2} - 1}

= \frac{1}{( 3 x ^{2} - 1 ) ^{2} + 1} \cdot \frac{3 x}{3 x ^{2} - 1}

Simplify

\frac{1}{( 3 x ^{2} - 1 ) ^{2} + 1} \cdot \frac{3 x}{3 x ^{2} - 1} : \frac{1}{x 3 x ^{2} - 1}

= \frac{1}{x 3 x ^{2} - 1}

y^{^{''}} + 3 y = 5

y^{^{''}} + y = \frac{1}{2 k ^{2}} (1 + cos (2 t))

\frac{d}{d x} ((x^{5} + 1)^{4})

f (x) = \frac{1}{x}, at x = 81

arccos (x) + x, at x = 0
