Differentiate with respect to $y$: $f(x,y,z) = sin(x)sin(y)sin(z)-cos(x)cos(y)cos(z)$
$begingroup$
The derivative with respect to $y$ of
$$f(x,y,z) = sin(x)sin(y)sin(z)-cos(x)cos(y)cos(z)$$
is
a) $f’(x,y,z) = cos(x)cos(y)sin(z) + sin(x)sin(y)cos(z)$
b) $f’(x,y,z) = sin(x)cos(y)sin(z) + cos(x)sin(y)cos(z)$
c) $f’(x,y,z) = cos(x)cos(y)cos(z) + sin(x)sin(y)sin(z)$
d) $f’(x,y,z) = sin(x)sin(y)sin(z) + cos(x)cos(y)cos(z)$

If we differentiate with respect to $y$ the other variables are assumed to be constant, so we get
$$frac{partial f(x,y,z)}{partial y}=cos(y)sin(x)sin(z)+sin(y)cos(x)cos(z)$$
