- ∂u/∂t = α∂²u/∂x² (heat equation)
Step 2: Specify Variables
Choose the variables with respect to which the derivatives will be calculated.
Step 3: Choose Type of Calculation
- Partial derivative
- Gradient
- Laplace operator
- Divergence
Step 4: Click “Calculate”
The calculator instantly computes:
- Partial derivatives
- Solution to the PDE (if applicable)
- Step-by-step explanation (optional)
Step 5: Review the Result
Analyze the output and, if necessary, use it to solve boundary or initial value problems.
Example: Using the Partial Differential Calculator
Scenario:
- Function: u(x, y) = x²y + e^(xy)
- Find ∂u/∂x and ∂²u/∂x∂y
Steps:
- Enter u(x, y) = x²y + e^(xy) in the calculator.
- Choose ∂/∂x for the first derivative.
Result:
- ∂u/∂x = 2xy + y*e^(xy)
Next, calculate mixed partial derivative ∂²u/∂x∂y:
- ∂²u/∂x∂y = 2x + e^(xy) + xy*e^(xy)
This process is fast and eliminates errors in manual calculations, especially for complex expressions.
