    a sketch of the graph will be helpful here|dw:1443658778182:dw|

    reflecting over the y-axis gives us:|dw:1443658820875:dw|

    I am asuming that it is true because if you cut the graph in half and flipped it over the y axis it will match up and if you did the same thing over the x axis it would be the same just on the other side

    wait so its not the same then because when you reflect over the y axis it moves over

    notice what happens when you reflect over the x-axis

    so either way is going to be different, Reflecting y=cos x over the x axis is different and the y axis reflection is also different in comparison to the origional graph.

    almost, notice what happens when you reflect over the y-axis

    (since cos(x) is symmetric about the y-axis, reflecting over the y-axis does nothing while reflecting over the x-axis changes the graph)
