sin-1290

OpenStudy (phi):

do you mean \[ \sin^{-1}\left(290^o\right) \]

OpenStudy (phi):

I would use a calculator

geerky42 (geerky42):

Or is it \(\sin(-1290^o)\) ?

OpenStudy (mathmale):

I'd definitely interpret 'sin-1290' as geerky42 has done. Do you know the word "coterminal" as in "What is the angle closest to zero that is coterminal with the angle -1290 degrees?
