(\partial)/(\partial y)(tan(1+2x^2y^4z^2))

\frac{\partial}{\partial y} (tan (1 + 2 x^{2} y^{4} z^{2}))

sec^{2} (1 + 2 x^{2} y^{4} z^{2}) \cdot 8 x^{2} z^{2} y^{3}

Solution steps

\frac{\partial}{\partial y} (tan (1 + 2 x^{2} y^{4} z^{2}))

Treat

x, z

as constants

Apply the chain rule:

sec^{2} (1 + 2 x^{2} y^{4} z^{2}) \frac{\partial}{\partial y} (1 + 2 x^{2} y^{4} z^{2})

= sec^{2} (1 + 2 x^{2} y^{4} z^{2}) \frac{\partial}{\partial y} (1 + 2 x^{2} y^{4} z^{2})

\frac{\partial}{\partial y} (1 + 2 x^{2} y^{4} z^{2}) = 8 x^{2} z^{2} y^{3}

= sec^{2} (1 + 2 x^{2} y^{4} z^{2}) \cdot 8 x^{2} z^{2} y^{3}

f (x) = 3 sin (x) + ln (5 x)

\int_{- 2}^{2} 4 - x^{2} d x

x \to 2 lim (e^{\frac{1}{2 - x}})

y = 2 + \frac{1}{x}, (2, 2.5)

\int csc^{8} (x) d x
