(\partial)/(\partial x)(sin(nx)e^{-ny})

\frac{\partial}{\partial x} (sin (n x) e^{- n y})

e^{- n y} cos (n x) n

Solution steps

\frac{\partial}{\partial x} (sin (n x) e^{- n y})

Treat

n, y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= e^{- n y} \frac{\partial}{\partial x} (sin (n x))

Apply the chain rule:

cos (n x) \frac{\partial}{\partial x} (n x)

= cos (n x) \frac{\partial}{\partial x} (n x)

\frac{\partial}{\partial x} (n x) = n

= e^{- n y} cos (n x) n

x^{8} e^{x}

\int x + 4 d x

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

\int 6 + 6 x + 36 x^{2} d x

f^{^{'}} (x) = x - 3
