Introduction to Gradient Calculator
Gradient Calculator is an online multivariable tool that helps you find the vector function of multivariable using first order partial differential method in no time.
Our gradient vector calculator is used to evaluate the gradient on different points on straight lines whose components are in different variables in partial derivative functions.
While the Gradient Calculator deals with scalar fields and their gradients, the curl of a vector field calculator deals with vector fields and their curl. Despite operating on different types of fields, both calculators are essential tools in vector calculus and are often used in tandem to analyze and understand the behavior of vector and scalar fields in multivariable contexts
What is a Gradient?
The gradient is a vector function that contains the first order of partial derivative of multivariable function like two variables f(x,y) or three variables f(x,y,z) in the second dimension or third dimension respectively.
The gradient is an operator whose symbol is a nebula “∇”. When the gradient goes from left to right in the vector line it gives a positive gradient otherwise it gives a negative gradient.
While the Gradient Calculator deals with scalar fields and their gradients,Further, if you would like to find the divergence of function in a vector field and provides a solution in the scalar function. You can use our divergence convergence calculator. Our calculator also evaluates the vector field whose flux magnitude is in a directionless system in a fraction of a second.
Notation Behind Gradient Vector Calculator
For the gradient of vector function partial fraction differential method for two variables function in 2-D and three variables in 3-D. Our gradient calculator uses the following formula to solve gradient vector problems,
$$ \nabla f(x,y) \;=\; \biggr( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y} \biggr) $$
$$ \nabla f(x,y,z) \;=\; \biggr( \frac{\partial f}{\partial x} \frac{\partial f}{\partial y} \frac{\partial f}{\partial z} \biggr) $$
Whereas,
- f(x,y) is two variable function along the x and y variables
- f(x,y,z) is three variable function along the x,y, and z variables.

Evaluation Process of Gradient of a Line Calculator
The gradient function calculator uses the partial differential method to find out the solution to different kinds of variable functions for two points or three points on a vector straight line on the graph. This is due to because our tool is well-equipped with partial differential rules in its programs.
You just need to add your given vector function and the gradient descent calculator will automatically detect the vector function behavior and provide a solution according to function conditions.
When you give the input function, the gradient of a function calculator identifies the gradient problem before starting the evaluation process. After analyzing the multivariable function, the calculator takes partial differential one by one along with x, y, and z variables separately.
Now the gradient formula calculator gets the partial derivative of the gradient function and to find the value of gradient points, it adds all points in its respective variables function. After adding the points, the calculator gives the solution of a gradient vector function with point values.
Let us see an example of a gradient function along with different variables to get better clarity about this concept and the working procedure of the gradient calculator. Additionally, you can explore further mathematical tools like the taylor approximation calculator for more advanced calculations.
Examples of Gradient Problems
An example of a gradient vector function solution with a complete explanation is given below. The example is for understanding the manual way of calculating such problems. As the gradient of a line calculator gives fast and accurate solutions but its important to understand the manual calculation,
Example no 1.
Find the gradient of f(x,y,z)=xy+yz+xz. Then find the gradient at point P(1,2,3)?
Solution:
To determine the gradient of f(x,y,z) = xy + yz + xz, we will calculate the partial derivative first,
Partial derivatives wit respect to x:
$$ \frac{\partial f}{\partial x} \;=\; y + z $$
Partial derivative with respect to y:
$$ \frac{\partial f}{\partial y} \;=\; x+z $$
Partial derivative with respect to z:
$$ \frac{\partial f}{\partial z} \;=\; x+y $$
Now assemble these into the gradient vector:
$$ \nabla f(x,y,z) \;=\; \biggr( \frac{\partial f}{\partial x}, \frac{\partial f}{\partial y}, \frac{\partial f}{\partial z} \biggr) \;=\; (y+z, x+z, x+y) $$
Now we will substitute x=1, y=2 and z=3 into the gradient expression:
$$ \nabla f(1,2,3) \;=\; (2+3, 1+3, 1+2) \;=\; (5,4,3) $$
Example no 2:
Find the gradient of f(x,y)=3x^2+y^3−3x+y. Then find it's value at the point P(2,3)?
Solution:
To determine the gradient of f(x,y) = 3x^2 + y^3 - 3x + y, we will calculate the partial derivative first,
Partial derivative with respect to x:
$$ \frac{\partial f}{\partial x} \;=\; 6x-3 $$
Partial derivative with respect to y:
$$ \frac{\partial f}{\partial y} \;=\; 3y^2 + 1 $$
Assemble these into the gradient vector:
$$ \nabla f(x,y) \;=\; \biggr(\frac{\partial f}{\partial x}, \frac{\partial f}{\partial y} \biggr) \;=\; (6x - 3, 3y^2 + 1) $$
To find the value at the point P(2,3), we substitute x=2 and y=3 into the gradient expression:
$$ \nabla f(2,3) \;=\; (6(2) - 3, 3(3)^2 + 1) \;=\; (9,28) $$
