Question

what is the value for
cos^{-1}(x)*cos^{-1}(1/x)
pl i will mark u as brainlyest..
check the points that u r awarded ​

Answer 1

Answer:

pls thank me mark as brainliest

Step-by-step explanation:

=cos^{-1}(x)×cos^{-1}(1/x)

=cos^{-1}(x)×sec^{-1}(x). (cos^{-1}(1/x)=sec^{-1(x))

=1/cos(x)×cos(x). (cos^{-1}(x)=1/cos(x))

=1. (sec^{-1(x)=cos(x))

Answer 2

Answer:

= cos ^{-1}(x)× cos^{-1}(1/x)

=cos^{-1}(x)×sec^{-1}(x) (cos^(-1)(1/

X) =sec^{-1(x)}

=1/cos (x)×cos (x). (cos^(-1)(x)=1/

Cos(x)

= 1. (sec^(-1(x)=cos(x)
