How do I find the missing value ?
\(\bf tan(\square )=38\implies tan^{-1}[tan(\square )]=tan^{-1}(38)\implies \square =tan^{-1}(38)\)
wait im confused :/
... ok where?
the whole equation you put up there
do you know what an inverse function is? like say \(\bf sin^{-1}\qquad cos^{-1}\qquad tan^{-1}\quad ?\)
no
do you happen to have them in your calculator btw? do you see any buttons with those labels \(\bf [sin^{-1}]\qquad [cos^{-1}]\qquad [tan^{-1}]\quad ?\)
yes
i guess that im just having trouble understanding how to find the missing value exactly i dont know if you can understand what im trying to say
ok well \(\bf sin^{-1}({\color{red}{ whatever}})\implies \textit{what is the angle WHOSE sine is }{\color{red}{ whatever}} \\ \quad \\ cos^{-1}({\color{red}{ whatever}})\implies \textit{what is the angle WHOSE cosine is }{\color{red}{ whatever}} \\ \quad \\ tan^{-1}({\color{red}{ whatever}})\implies \textit{what is the angle WHOSE tangent is }{\color{red}{ whatever}}\)
\(\bf tan({\color{red}{ angle}})={\color{blue}{ value}}\implies tan^{-1}({\color{blue}{ value}})={\color{red}{ angle}} \\ \quad \\ tan^{-1}[tan({\color{red}{ angle}})]={\color{red}{ angle}}\)
thus \(\bf tan(\square )=38\implies tan^{-1}[tan(\square )]=tan^{-1}(38)\implies \square =tan^{-1}(38)\)
god i dont know if im slow today or you're not very good explaining this whatever it is im not getting it
nevermind i think i get it now lol
