Python rs_series_reversion Examples

Example #1

File: test_ring_series.py Project: mayou36/sympy

def test_series_reversion():
    R, x, y = ring('x, y', QQ)

    p = rs_tan(x, x, 10)
    assert rs_series_reversion(p, x, 8, y) == rs_atan(y, y, 8)

    p = rs_sin(x, x, 10)
    assert rs_series_reversion(p, x, 8, y) == 5*y**7/112 + 3*y**5/40 + \
        y**3/6 + y
