Question
if 8 sin 2 x + 3 cos 2 x = 4
 then find tan xSolution
8 sin2 x + 3 cos2 x = 4 ----- (1) Now we know that sin2 x + cos2 x = 1 or 8 sin2 x + 8 cos2 x = 8 ----(2), So by solving equation (1) & (2), we will get, cos2 x = 
or cosx = Putting the value of cosx in equation (1), we will get sin x = so tan x = = =
