(\partial)/(\partial x)(x^2+3)

解答

\frac{\partial}{\partial x} (x^{2} + 3)

2 x

求解步骤

\frac{\partial}{\partial x} (x^{2} + 3)

使用微分加减法定则:

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

= \frac{\partial}{\partial x} (x^{2}) + \frac{\partial}{\partial x} (3)

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

\frac{\partial}{\partial x} (3) = 0

= 2 x + 0

化简

= 2 x

9 y^{^{''}} + 9 y = 0

t an g e n t f (x) = sin (π - x), at x = \frac{π}{6}

\frac{\partial}{\partial y} (x^{2} + y^{2} + 1)
