(d^2)/(dx^2)(sin(9x^2))

\frac{d ^{2}}{d x ^{2}} (sin (9 x^{2}))

18 (- 18 x^{2} sin (9 x^{2}) + cos (9 x^{2}))

Solution steps

\frac{d ^{2}}{d x ^{2}} (sin (9 x^{2}))

\frac{d}{d x} (sin (9 x^{2})) = cos (9 x^{2}) \cdot 18 x

= \frac{d}{d x} (cos (9 x^{2}) \cdot 18 x)

\frac{d}{d x} (cos (9 x^{2}) \cdot 18 x) = 18 (- 18 x^{2} sin (9 x^{2}) + cos (9 x^{2}))

= 18 (- 18 x^{2} sin (9 x^{2}) + cos (9 x^{2}))

n = 1 \sum \infty 1 0^{n} x^{n} n!

2 x + 5

\int (1 + x^{3}) d x

\int_{- 1}^{1} 3 x^{2} x^{3} + 1 d x

\frac{d}{d x} ((1 + x^{4})^{\frac{2}{3}})
