Needhelp2013 said:I tried substituting what 'z=' into the laplace equation but that didnt get me anywhere.
bossman27 said:Exactly what I meant by thinking too hard. All that it's asking you to do is show that if you take the derivative of z with respect to x and then y, it's the same as taking the derivative of z with respect to y and then x. In other words, show:
[itex]\frac{\partial}{\partial y}(\frac{\partial z}{\partial x}) = \frac{\partial}{\partial x}(\frac{\partial z}{\partial y}) [/itex]
Does that make any more sense now?
bossman27 said:You can't read that equation? It should read: ∂/∂y(∂z/∂x) = ∂/∂x(∂z/y)
A partial differential equation (PDE) is a mathematical equation that involves multiple independent variables and their partial derivatives. It is used to describe how a system changes over time and space.
Partial differential equations can be complex and difficult to solve, making them challenging for scientists and mathematicians. Seeking help from others can offer new perspectives and approaches to solving these equations.
Some common techniques for solving partial differential equations include separation of variables, Fourier transforms, and numerical methods such as finite differences and finite elements.
Partial differential equations are used in many areas of science, such as physics, engineering, and biology. They can be used to model and understand complex systems and phenomena, making them a powerful tool for scientific research.
In some cases, partial differential equations can be solved analytically, meaning a closed-form solution can be found. However, for more complex equations, numerical methods are often used to approximate the solution.
