sint
Sine by tau approximation for itau object.
Syntax
[F, e, n] = sint(x)
Description
F = sint(x) is a function to approximate by tau method sin(x), x in
[a, b]. This function goal is to take the machine precision in this
approximation, once sint(x) can be a funcional coeefficient at the
equation. For this porpouse, we are using schursolver function, which
will decide the approximation degree to achieve 1e-16. Concluding, now
is possible to use sint(x) as coefficient.
Input
x = independent tau variable (itau object).
Output
F = polynomial approximation of sin(x) in [a, b] evaluated (with
orthovalM) in argument M = matrixM(x) (double matrix).
See also
sinht, cost, cosht, expt and logt.
