In 1977 Hubbard developed the ideas of Cayley (1879) and solved
in particular the Newton-Fourier imaginary problem. We solve the
Newton-Fourier and the Chebyshev-Fourier imaginary problems
completely. It is known that the application of Julia set theory
is possible to the one-dot numerical method like the Newton's
method for computing solution of the nonlinear equations. The
secants method is the two-dots numerical method and the
application of Julia set theory to it is not demonstrated.
Previously we have defined two one-dot combinations: the
Newton's-secants and the Chebyshev's-secants methods and have
used the escape time algorithm to analyse the application of
Julia set theory to these two combinations in some special cases.
We consider and solve the Newton's-secants and
Tchebicheff's-secants imaginary problems completely.
