Question

Find the exact value of tan5^-1 (1)

Answer 1

\(\bf tan^{-1}(1)\quad ?\)

Answer 2

nah theres a 5 before the -1

Answer 3

thats why im confused

Answer 4

can you post a picture of it?

Answer 5

makes no sense to me

Answer 6

tis a typo, is noticeable due to the choices given

Answer 7

keep in mind that the ^ is next to the "5" on the keyboard =)

Answer 8

LOL

Answer 9

so just 7pi/4 then?

Answer 10

\(\bf tan^{-1}(1)\implies tan(\theta)=1\implies tan^{-1}(tan(\theta))=tan^{-1}(1)\\ \quad \\
\theta=tan^{-1}(1)\)

yes, that one would work

keep in mind that for the inverse tangent function, its domain is \(\bf \left(\cfrac{\pi}{2},-\cfrac{\pi}{2}\right)\) so that would fall under that range

Answer 11

thanks
