(\partial)/(\partial y)(x^2+y^2-13)

\frac{\partial}{\partial y} (x^{2} + y^{2} - 13)

2 y

Solution steps

\frac{\partial}{\partial y} (x^{2} + y^{2} - 13)

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (x^{2}) + \frac{\partial}{\partial y} (y^{2}) - \frac{\partial}{\partial y} (13)

\frac{\partial}{\partial y} (x^{2}) = 0

\frac{\partial}{\partial y} (y^{2}) = 2 y

\frac{\partial}{\partial y} (13) = 0

= 0 + 2 y - 0

Simplify

= 2 y

f (x) = - x^{2} - 7 x + 44, at x = 2

\int - e^{3 x} d x

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

\int \frac{y}{x z} d x

\frac{s + 2}{( s - 2 ) ( s + 1 )}
