sec(tan^-1(1))=

OpenStudy (sidsiddhartha):

first tell me which angle of tan has a value of 1

OpenStudy (sidsiddhartha):

\[\tan(?)=1\]

OpenStudy (anonymous):

dont know

OpenStudy (sidsiddhartha):

ok u need to know basic trig angle values to solve this problem \[\tan45=1\] so we can write it as \[\sec(\tan^{-1}(1))=\sec(\tan^{-1}[\tan 45])\]

OpenStudy (anonymous):

the answers are 1/2 \[\sqrt{3/2}\] \[\sqrt{2}\]\[\sqrt{2}\]

OpenStudy (sidsiddhartha):

yes let me explain to u a bit ok!!

OpenStudy (anonymous):

we have to suppose the value?

OpenStudy (anonymous):

ok

OpenStudy (sidsiddhartha):

no these are standard values check this out

OpenStudy (anonymous):

ok

OpenStudy (sidsiddhartha):

now we need another propery \[\tan^{-1}(\tan~\theta)=\theta\]

OpenStudy (sidsiddhartha):

so according to this property \[\tan^{-1}(\tan~45^0)=?\] can u tell me?

OpenStudy (anonymous):

1

OpenStudy (sidsiddhartha):

no |dw:1415093338469:dw| make sense?
