Answer :

Given: cos x = = and <x<.i.e, x lies in II quadrant


To Find: i)sin ii)cos iii)tan


i) sin


Formula used:


sin =


Now, sin = = =


Since sinx is positive in II quadrant, hence sin


ii)cos


Formula used:


cos =


now, cos = = = = =


since cosx is negative in II quadrant, hence cos =


iii)tan


Formula used:


tan x =


hence, tan = = = = -


Here, tanx is negative in II quadrant.
