Let sin(x) = 8/ 11 and /2 < x < . Find the other five trig values for x.
Solution
sin(x) = 8/ 11 and /2 < x <
x is in IInd quadrant , cosx and tanx are -ve
base of right angled traingle = sqrt(11^2 -8^2) = sqrt57
cosx = -sqrt(57)/11
secx = 1/cosx =-11/sqrt(57)
tanx = -8/sqrt(57)
cotx = sqrt57/8
cscx = 1/sinx = 11/8
