Question 1022067: Use your trig identities and the given information to determine the exact value
Cosx=1/4,0< Or equal to x< Or equal to 90 find cscx Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! If cos x = 1/4
and sin^2 x + cos^2 x = 1, we can see that
sin^2 x = 1 - (1/4)^2 = 1 - 1/16 = 15/16
That means
sin x = sqrt(15) / 4 and
csc x = 4 / sqrt(15) = 4*sqrt(15) / 15
