Solve -2sin(x)cos(x)=0 in radians

Would i just split it up into two parts? So it would be sin(x)=0 and cos(x)=0, and then the answer would be 0, ╥, 2╥, ╥/2, and 3╥/2 ?
Can I have the exact answer from the unit circle?
("Alt210" gives you the pi symbol)

Yes, these problems are a little strange, but you would "solve it twice".

First, divide by -2 sin x:

cos x = 0

What values cause cos to equal 0? pi/2 and 3pi/2

Now divide each side by -2cos x:

sin x = 0

What values make sin = 0? 0 and pi!

You have four solutions. You did it right.
