## Frequently Asked Questions

### Is partial differential equations hard?

Yes, the partial differential equations are hard to solve. But when these equations are converted into ordinary differential equations, we can evaluate them with different methods or by using partial differential calculator.

### What is the difference between ordinary differential equations and partial differential equations?

The ordinary differential equations (ODEs) are those equations where the derivatives are taken with respect to one independent variable. Whereas the partial differential equations (PDE’s) are those equations where the derivatives are taken with respect to more than one variables.

### What is first order partial derivatives?

The derivative of a multivariable function with respect to an independent variable one time, is known as first order partial derivative. In partial derivative, we differentiate a function with one variable by treating other as a constant. We can use first order partial derivatives calculator to solve them online.

### What is continuous first order partial derivatives?

The partial derivative of a continuous function is known as continuous partial derivative if the derivative is also continuous. But for a continuous function, it is not necessary that its derivative should also be continuous.

### What is elliptic partial differential equations?

A second order partial differential equation (PDE)

Au_{xx}+2Bu_{xy}+Cu_{yy}+Du_{x}+Fu_{y}+G=0 is considered as elliptic if, B^{2}−AC < 0. Elliptic partial differential equations have no real characteristic surfaces.

You can use partial differential equations calculator above to solve your equations online.

### What is the chain rule of partial differentiation?

The chain rule partial differentiation is a technique in which we differentiate a function with respect to two or three variables at a time.

For a function f=f(u,v), u=u(x,y) and v=v(x,y) the chain rule is,

$$ \frac{df}{dx} \;=\; \frac{df}{du}\frac{du}{dx} \;+\; \frac{df}{dv}\frac{dv}{dx} $$

And,

$$ \frac{df}{dy} \;=\; \frac{df}{du}\frac{du}{dy} \;+\; \frac{df}{dv}\frac{dv}{dy} $$
