Partial Derivatives

2. Partial Derivatives

3. First Order Partial Derivatives
fx(x,y)=Derivative(f(x, y),x)
fy(x,y)=Derivative(f(x, y),y)

4. Derivative(f(x, y),x)
Derivative(f(x, y),y)

5. fx(x,y)=Derivative(f, x)
fy=Derivative(f, y)
fy(-1,3)

6. Second Order Partial Derivatives

7. fx(x,y)=Derivative(f, x)
fy(x,y)=Derivative(f, y)
fxx(x,y)=Derivative(fx, x)
fyx(x,y)=Derivative(fy, x)
fxy(x,y)=Derivative(fx, y)
fyy(x,y)=Derivative(fy, y)
fxy(1,2)
fyy(1,2)

9. fx(x,y)=Derivative(f(x, y),x)
fy=Derivative(f,y)
fy(125,27)
