(\partial)/(\partial x)(sin(3x)cos(4y))

\frac{\partial}{\partial x} (sin (3 x) cos (4 y))

cos (4 y) cos (3 x) \cdot 3

Solution steps

\frac{\partial}{\partial x} (sin (3 x) cos (4 y))

Treat

y

as a constant

Take the constant out:

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

= cos (4 y) \frac{\partial}{\partial x} (sin (3 x))

Apply the chain rule:

cos (3 x) \frac{\partial}{\partial x} (3 x)

= cos (3 x) \frac{\partial}{\partial x} (3 x)

\frac{\partial}{\partial x} (3 x) = 3

= cos (4 y) cos (3 x) \cdot 3

(- 3.1) (- 17.2)

\int_{0}^{2} x^{2} e^{x} d x

e^{3}

\int 9 x 1 + 2 x^{2} d x

n \to \infty lim (0)
