Answer 1

square both sides, what do you get?

Answer 2

sin^2(X) +2sin(x)cos(x)+ cos^2(x) =1

Answer 3

ohhh 1+sin(2x) =1

Answer 4

ohhh no

Answer 5

don't go that way, 2sinx cosx =0 then either sinx =0 or cos x =0. solve for them.

Answer 6

oh got it , so its's 0 and pi/2?

Answer 7

pi/2, pi, 3pi/2,

Answer 8

on your problem \(0\leq x\leq 2\pi\) or just \(0<x<2\pi\)?

Answer 9

equal or not?

Answer 10

0≤x≤2π

Answer 11

ok, so take 0 and 2pi also

Answer 12

oh got it, thanks! :)
