QUESTION: 3

Which of the following is one of the criterions for linearity of an equation?

Solution:

The two criterions for linearity of an equation are:

QUESTION: 4

Solution:
QUESTION: 5

For a partial differential equation, in a function φ (x, y) and two variables x, y, what is the form obtained after separation of variables is applied?

Solution:

The method of separation of variables relies upon the assumption that a function of the form,
Φ (x, y) = X(x)Y(y)
will be a solution to a linear homogeneous partial differential equation in x and y. This is called a product solution and provided the boundary conditions are also linear and homogeneous this will also satisfy the boundary conditions.
