Question

\[\sec^−1(−x)=π+\sec ^{-1}\] ? why?

Answer 1

equation incomplete ...what is the argument on the left side?

Answer 2

I mean right

Answer 3

LOL

Answer 4

why this things equal

Answer 5

arcsec(-x) = π+ arcsec(-x or x) what is the question?

Answer 6

proof this equation, if x>= 1.

Answer 7

you didn't answer my question ... the right side argument is x or -x ? you didn't put any argument after arcsec ...

Answer 8

oh sorry , it's x

Answer 9

thanks for reply :D

Answer 10

ok ...

Answer 11

arcsec(-x) = π+arcsec(x) right ?

Answer 12

yes

Answer 13

do you know the range and the domain of arcsecx

Answer 14

yes

Answer 15

you have to prove the eq if x≥1?

Answer 16

what math class are you in ... ? trig or calc?

Answer 17

arcsec(1) = 0, arcsec(-1) = π

Answer 18

π =π+0
