(\partial)/(\partial x)(tan(9+2x^2y^4z^2))

\frac{\partial}{\partial x} (tan (9 + 2 x^{2} y^{4} z^{2}))

sec^{2} (9 + 2 x^{2} y^{4} z^{2}) \cdot 4 y^{4} z^{2} x

Solution steps

\frac{\partial}{\partial x} (tan (9 + 2 x^{2} y^{4} z^{2}))

Treat

y, z

as constants

Apply the chain rule:

sec^{2} (9 + 2 x^{2} y^{4} z^{2}) \frac{\partial}{\partial x} (9 + 2 x^{2} y^{4} z^{2})

= sec^{2} (9 + 2 x^{2} y^{4} z^{2}) \frac{\partial}{\partial x} (9 + 2 x^{2} y^{4} z^{2})

\frac{\partial}{\partial x} (9 + 2 x^{2} y^{4} z^{2}) = 4 y^{4} z^{2} x

= sec^{2} (9 + 2 x^{2} y^{4} z^{2}) \cdot 4 y^{4} z^{2} x

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

\frac{1}{8} x, \frac{1}{x ^{2}}, x

x \to \infty lim (ln (5 x^{2} + 12 x - 6))

\int e^{9 x} sin (x) d x

\int_{2}^{\infty} - 3 x^{- 2} d x
