FORMATION OF PARTIAL DIFFERENTIAL
EQUATIONS BY ELIMINATION OF ARBITRARY FUNCTIONS
§
Explain the formation of p.d.e. by elimination of arbitrary functions.
Solution
:
Suppose two functions u & v are connected by the relation
§
What can you say about the order of p.d.e. got by eliminating arbitrary
functions?
Solution:
The elimination of one arbitrary function will result in a p.d.e. of the first
order. The elimination of two arbitrary functions will result in equations of
second order and so on.
