Aug 30, 2015 (delw)/(delx) = x/sqrt(x^2 + y^2 + z^2) (delw)/(dely) = y/sqrt(x^2 + y^2 + z^2) (delw)/(delz) = z/sqrt(x^2 + y^2 + z^2) Since you're dealing with a multivariable function, you must treat x, y, and z as independent variables and calculate the partial derivative of w, your dependent variable, with respect to x, y, and z. When you differentiate with respect to x, you treat y and z as constants

Answer (1 of 3): I assume you want to integrate this: \displaystyle{\iint\dfrac{x}{\sqrt{x^2+y^2}}dxdy} We should probably switch to polar coordinates, because {\sqrt{x^2+y^2}}is an expression that perfectly relates polar and Cartesian coordinate systems. Let x=r\cos(\theta)and y=r\sin(\theta)

Answer (1 of 2): The context appears to be classical (Lagrangian) mechanics. The overdot is just shorthand for differentiation with respect to time. That is, \dot{x}\equiv dx/dt, for instance. More importantly, what you are differentiating is the action. In Lagrangian physics, the action is tre

The square root keeps us from going above that point z=4. if we manipulate the equation and isolate x 2 + y 2 we get. x 2 + y 2 = 16 - z 2. (remember that since we have a square root in our original function, we have to consider it's domain in our graph, meaning z =4) This is the equation of a cone so we now know what we are looking at

Jun 22, 2015 To find d/dx(sqrt(x^2+y^2)), as part of an implicit differentiation problem, use the chain rule. d/dx(sqrtx) = 1/(2sqrtx), so d/dx(sqrtu) = 1/(2sqrtu) (du)/dx. d/dx(sqrt(x^2+y^2)) = 1/(2sqrt(x^2+y^2)) * d/dx(x^2+y^2) = 1/(2sqrt(x^2+y^2))(2x+2y dy/dx) =1/(2sqrt(x^2+y^2))2x+ 1/(2sqrt(x^2+y^2))2y dy/dx =x/sqrt(x^2+y^2)+ y/sqrt(x^2+y^2) dy/dx In order to solve for dy/dx you will, of course, need

x 2 + y 2 = z 2. Subtract y^ {2} from both sides. Subtract y 2 from both sides. x^ {2}=z^ {2}-y^ {2} x 2 = z 2 − y 2. Take the square root of both sides of the equation. Take the square root of both sides of the equation. x=\sqrt {\left (z-y\right)\left (y+z\right)} x=-\sqrt {\left (z-y\right)\left (y+z\right)}
