Find the value of other five trigonometric function `cosx=-1/2,` x lie – InterviewSolution

InterviewSolution

1.	Find the value of other five trigonometric function `cosx=-1/2,` x lies in third quadrant.
Answer» In the third quadrant, only `tanx` and `cotx` will be positive. Rest will be negative. Here,`cosx = -1/2` `sinx = sqrt(1-cos^2x) = sqrt(1-1/4) = sqrt(3/4) = -sqrt3/2` `tanx = sinx/cosx = sqrt3` `cotx = 1/tanx = 1/sqrt3` `secx=1/cosx = -2` `cosecx = 1/sinx = -2/sqrt3`
