(\partial)/(\partial x)(7sin(x)sin(y))

\frac{\partial}{\partial x} (7 sin (x) sin (y))

7 sin (y) cos (x)

Solution steps

\frac{\partial}{\partial x} (7 sin (x) sin (y))

Treat

y

as a constant

Take the constant out:

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

= 7 sin (y) \frac{\partial}{\partial x} (sin (x))

Apply the common derivative:

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

= 7 sin (y) cos (x)

What is (\partial)/(\partial x)(7sin(x)sin(y)) ?
The answer to (\partial)/(\partial x)(7sin(x)sin(y)) is 7sin(y)cos(x)
