Question

what is sin^-1(sin (pi/11)

Answer 1

Wouldn't it be pi/11?
arcsin has a domain of -1 to 1

Answer 2

thank you, so would tan^-1(tan-pi/3) = -pi/3

Answer 3

wait.. is this trig or calculus? :/

Answer 4

this it trig

Answer 5

@katmartins trig or calc?

Answer 6

Haha, smartypants :P

Answer 7

^___^

Answer 8

@Luigi0210 this is trig

Answer 9

it is \(\frac{\pi}{11}\) since
\[-\frac{\pi}{2}<\frac{\pi}{11}<\frac{\pi}{2}\]

Answer 10

yea, arctans domain is what satellite has shown

Answer 11

same for tan^-1(tan-pi/3)? does that equal -pi/3

Answer 12

Hm, I guess so
