Question

Evaluate: sin(Arcsec 1)

Answer 1

Arcsec 1 = 0
sin 0 = 0

Answer 2

arcsec x = 1/cos x

Answer 3

sec x = 1/cos x

Answer 4

hamed is right! :)

Answer 5

:)

Answer 6

damn, i said sec so arcsec is actually meant to be ???

Answer 7

sec(arcsec1)= 1 => 1/cos(arcsec1) = 1 => cos(arcsec1)=1 => sin(arcsec1) = 0 (for example because sin^2 + cos^2 = 1)

Answer 8

heres the other 2 traingles
i figure more examples the same way would help
