If `tanx=3/4` ,`pi lt xlt (3pi)/ 2`, then find the value of `cos (x/2)`

If tan x = 3/4, pi lt x lt (3pi)/(2), then the value of cos ""x/2 is

If tanx=3/4, pi lt x lt (3 pi)/(2) , then the value of cos. x/2 is

If tan x = (3)/(4), pi lt x lt (3pi)/(2) , then the value of cos""(x)/(2) is

If tan x = 3/4, pi lt x lt (3pi)/(2), find the value of sin (x)/(2), cos "" x/2 and tan "" x/2.

If tan x = 3/4, pi lt x lt (3pi)/(2), find the vlaue of sin (x)/(2), cos "" pi/2 and tan "" x/2.

If tan x = 3/4, pi lt x lt (3 pi)/2 , find the values of sin frac (x)(2), cos frac (x)(2) and tan frac (x)(2) .
