Find all solutions in the interval [0.2?(pi)):
Sin ² 2x - cos ² x = 0
2 tan ² x - sec ² x + 3 = 1 - 2 tan x
Find all solutions of the equation:
? (3) sin 2x = cos 2x
(fyi: for this problem,
3 is under the square root symbol)
Tan ^5 x – 9 tan x=0
4 sinxcosx + 2 sin x - 2 cos x -1 =0
If you can answer at least one i would be most grateful
