Question

determine whether the function y=tan x/x^2 is even, odd, or neither

Answer 1

is it \[\tan \frac{ x }{ x^2}\] or \[\frac{\tan x }{ x^2}\]

Answer 2

the second one

Answer 3

so plug in -x for x and what do you get?

Answer 10

open your own question, @africa3

Answer 11

not you @bernardod , @africa3

Answer 12

ok

Answer 13

I put -x

Answer 14

no

Answer 15

even functions have\[f(-x)=f(x)\] whereas odd functions have \[f(-x)=-f(x)\]

Answer 16

so when you take f(-x), does your function look the same as the original function, a negative version of the original function, or neither?

Answer 17

no

Answer 18

so \[f(x) = \frac{ \tan x }{ x^2 }\Rightarrow f(-x) = \frac{ \tan (-x) }{(-x)^2 }=\frac{ -\tan x }{ x^2 }=-\frac{ \tan x }{ x^2 }\]

Answer 19

ooooo...I see

Answer 20

thanks!

Answer 21

learn to plug it in and work it out to see what you get! if you plug in -x for x and get f(x) then it's and even function. if you plug in -x and get -f(x) then it's an odd funcction. if you don't get either or those then it's neither even nor odd.
