ABSTRACT: The Chebyshev polynomials are harnessed as
functions of the one parameter of the nondimensionalized differential equation
for trinomial homogeneous linear differential equations of arbitrary order n that have constant coefficients and exhibit
vibration. The
use of the Chebyshev
polynomials allows calculation of the analytic solutions for arbitrary n in terms of the orthogonal Chebyshev polynomials to provide a more stable solution form and
natural sensitivity analysis in terms of one parameter and the initial
conditions in 6n + 7 arithmetic
operations and one square root.
