help with finding the two smallest nonnegative asymptotes and the smallest negative

okay, i only have a couple more problems. these 2 i find to be the hardest. Problem 2 is definately the hardest one for me. So any help will be much appreciated.

italics= anwsers i got right

underline= answers i got wrong

::**Problem 1**::

Find the first TWO non-negative asymptotes and the first negative asymptote of the graph of https://webwork.uncc.edu/webwork2_fi...22b824af51.png in radians

smallest non-negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png *0*

second non-negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png __pi/4__

first negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png __-pi/4__

::Problem 2::

Find the first TWO non-negative asymptotes and the first negative asymptote of the graph of https://webwork.uncc.edu/webwork2_fi...22b824af51.png in radians

smallest non-negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png __0__

second non-negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png __pi/3__

first negative asymptote: https://webwork.uncc.edu/webwork2_fi...9019052b81.png __-pi/3__

Help please? :confused:
