Enter Tor F depending on whether the statement is true or fa

Enter Tor F depending on whether the statement is true or false (You must enter T or F-- True and False will not work.) The range of tan(x) is all real numbers tan(x) and cot x are odd functions sec(x) and tan(x) are undefined for the same values of x sin(x) is odd and cos(x) is even

Solution

1)
True

-------------------------------------------------

2)
True cuz we know very well that tan is odd

So, 1/tan, i.e cot is also odd ...

TRUE

----------------------------------------------------------------

3)
True because we have sec^2 = 1 + tan^2
and thus, when tan is undefined, sec is also undefined

---------------------------------------------------------------

4)
True
