Gradient of a scalar point function
Webis the gradient of some scalar-valued function, i.e. \textbf {F} = \nabla g F = ∇g for some function g g . There is also another property equivalent to all these: \textbf {F} F is irrotational, meaning its curl is zero everywhere (with a slight caveat). However, I'll discuss that in a separate article which defines curl in terms of line integrals. The gradient theorem states that if the vector field F is the gradient of some scalar-valued function (i.e., if F is conservative), then F is a path-independent vector field (i.e., the integral of F over some piecewise-differentiable curve is dependent only on end points). This theorem has a powerful converse: It is straightforward to show that a vector field is path-independent if and only if the integral of th…

WebThe Gradient. The gradient is a vector operation which operates on a scalar function to produce a vector whose magnitude is the maximum rate of change of the function at the point of the gradient and which is pointed in the direction of that maximum rate of change. In rectangular coordinates the gradient of function f (x,y,z) is: WebNov 7, 2024 · In single variable scalar function $\ f(x)\ $ the sign of the derivative can tell you whether the function is increasing or decreasing at the point. I was trying to find an analogous concept in multi-variable scalar function $\varphi(\vec r)\ $ since its output is a scalar quantity just like in the single variable function. Now in these functions we have …
