The partial derivative of a functionf(x,y,…)with respect toxis defined as: ∂f∂x=limΔx→0f(x+Δx,y,…)−f(x,y,…)Δx Second and Higher-Order Partial Derivatives Second order partial derivatives measure the rate at which the first partial derivative changes. Our calculator serv...
Defining the partial derivative of a function at a point on a variable : The calculator computes the value of the expression in constantly decreasing steps until the desired accuracy is reached. At each approximation the incremental step of the variable ...
Hello, Given a function like ##z= 3x^2 +2y##, the partial derivative of z w.r.t. x is equal to: $$\frac {\partial z}{\partial x} = 6x$$ Let's consider the point ##(3,2)##. If we sat on top of the point ##(3,2)## and looked straight in the positive x-directio...
