(d^2)/(dx^2)(x^3+y^3)

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

6 x + 3 (2 y \frac{d y}{d x}^{2} + \frac{d ^{2} y}{d x ^{2}} y^{2})

Solution steps

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

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

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

\frac{d}{d x} (3 x^{2} + 3 y^{2} \frac{d y}{d x}) = 6 x + 3 (2 y \frac{d y}{d x}^{2} + \frac{d ^{2} y}{d x ^{2}} y^{2})

= 6 x + 3 (2 y \frac{d y}{d x}^{2} + \frac{d ^{2} y}{d x ^{2}} y^{2})

π^{2}

\int \frac{2}{3 x - 2} d x

\frac{d}{d x} ((sec (2 x))^{7})

5 - x^{2}, 2 - 2 x

\int (x^{2} + x)^{11} (2 x + 1) d x
