Best ResponseYou've already chosen the best response.0First try to just put in the value pi/4 and decide if the function is defined in that point

Best ResponseYou've already chosen the best response.0You see that sin pi/4 cos pi/4 equals zero so the function is undefined at pi/4 so what you want to do is to simplify the function

Best ResponseYou've already chosen the best response.0you can turn your denominator into\[(33(\frac{ cosx }{ sinx })\] then split the numerator into two different fractions\[\frac{ 3 }{ sinxcosx }  \frac{ \frac{ sinx }{ cosx } }{ sinxcosx }\]
