Gradient of cylindrical coordinates
WebOct 21, 2024 · How do I find the gradient of the following scalar field in cylindrical polar coordinates? $\\ f(x,y,z)=2z-3x^2-4xy+3y^2$ Should I express it in polar form first, then … 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:
