okay so welcome what i want to do is show you how to graph y equals negative 2 secant of pi x divided by 2. so to do a problem like this the main important thing remember is we need to graph our inverse function which is cosine so what iamp;#39;m going to do is iamp;#39;m going to kind of immediately think of this as negative 2 cosine of pi x divided by 2 and thatamp;#39;s going to help me graph it from what weamp;#39;re used to and then what iamp;#39;m going to do is just kind of make some necessary changes to my graph so by graphing the cosine of x i need to determine what my amplitude is which iamp;#39;m going to kind of go a little bit quicker with this because weamp;#39;ve already done a whole bunch of videos on how to graph cosine so the amplitude in this problem is 2. my period in this case is going to be 4 as iamp;#39;m going to do 2 pi divided by pi halves so you multiply by pi multiply by 2 over pi so you get 4. then iamp;#39;m going to check on my x scale and rememb
