If there is a question, we say that find all exact solutions of the trigonometric equation.
00:09
This is 2 sin square x minus sin x equal to 0.
00:15
So, if we take sin x as common, it will be 2 sin x minus 1 equal to 0.
00:22
So, either sin x equal to 0 and 2 sin x minus 1 equal to 0.
00:32
So, this is y, we have x.
00:43
This is graph of sin x.
00:44
So, we can see 0, 0, 2 pi.
00:47
At integral multiple of pi, sin x is 0.
00:51
So, from here, answer will be 0 and pi as 2 pi will not be included in the interval 0 to 2...
