lgbasallote · Answer

1/2? 1/2 what?

lgbasallote · Answer

i mean the unit..degree or radian

anonymous · Answer

Radians or degrees is an important specification; but I think it's safe to assume radians given the scale.

anonymous · Answer

Oh it doesn't really say

anonymous · Answer

I'll check :D

anonymous · Answer

I'm thinking it's radians... someone please help me :(

lgbasallote · Answer

do you know the arcsec of 1/2?

anonymous · Answer

No, it's not in the unit circle :(

lgbasallote · Answer

it is..isnt it?

unklerhaukus · Answer

secant  is  1/cosine  is   hypotenuse / adjacent

anonymous · Answer

Hmm... See, I thought when it asked for arcsec, it was asking for what angle I can get 1/cos of and get 1/2
Which means one of the angles in the unit circle would have to have 2 as the x value, doesn't it? Cuz the inverse of 1/2 is two. But none of them have this value :(
