EXERCISE
1.1(b) (1): Obtain the p.d.e by eliminating a,b,c from
Note: The answer is not unique, we can get other equivalent
partial differential equations.

EXERCISE
1.1(a) (3)
1.
Form the partial differential equations by eliminating the arbitrary constants
a,b & c from z= ax +by + cxy
Note: The answer is not
unique, we can get two other equivalent partial differential equations.
