Python T Examples

Example #1

def test__TR56():
    h = lambda x: 1 - x
    assert T(sin(x)**3, sin, cos, h, 4, False) == sin(x)**3
    assert T(sin(x)**10, sin, cos, h, 4, False) == sin(x)**10
    assert T(sin(x)**6, sin, cos, h, 6, False) == (-cos(x)**2 + 1)**3
    assert T(sin(x)**6, sin, cos, h, 6, True) == sin(x)**6
    assert T(sin(x)**8, sin, cos, h, 10, True) == (-cos(x)**2 + 1)**4

    assert T(sin(x)**8, sin, cos, h, 10, True) == (-cos(x)**2 + 1)**4

    # issue 17137
    assert T(sin(x)**I, sin, cos, h, 4, True) == sin(x)**I
    assert T(sin(x)**(2 * I + 1), sin, cos, h, 4, True) == sin(x)**(2 * I + 1)
