function fast_cos(t::Real)
    # Computes cos(pi*t) using a Chebyshev approximation.
    # This approximation is minimax optimal on [-1, 1].
    # By scaling by pi, we find an optimal approximation on
    # the entire range of cos(x). Because cos(x - pi) = -cos(x),
    # we can take the remainder with 2, and shift [0, 2] |-> [-1, 1],
