Graph: It approaches zero, but it never gets there (limit does not exist).

Asked by enotes on via web

• Math
Graph, It looks like y approaches 0 when x approaches 0, but x=0 is undefined.

Asked by enotes on via web

• Math
It is even. `cos-x=cos(0-x) ` `cos(0-x)=sin0sinx+cos0cosx=cosx ` Therefore, `cos ` is even `sec(-x)=1/cos-x ` This equals `1/cosx=secx ` Therefore, `sec ` is even

• Math
The graph of the functionis symmetric about origin.So it is an odd function. f(x)=tanx f(-x)=tan(-x) =-tanx =-f(x). f(-x)=-f(x).So the function is odd.
