Grad of f x

WebSep 18, 2024 · Remember that the value of f'(x) anywhere is just the slope of the tangent line to f(x). On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 … WebGradient of a scalar field Let f (x,y,z) be a scalar field. The gradient is a vector it is the derivative of f in each direction. The gradient of a scalar field is a vector field. An alternative notation is to use the del or nabla operator, Ñ f = grad f.
