Use a calculator to find all solutions in the interval (0, 2π). Round the answers to two decimal places. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
sin x cos x = 0.078
-----
Note: sin(2x) = 2sin(x)cos(x)
-------
Your Problem:
(1/2)sin(2x) = 0.078
----
sin(2x) = 0.156
----
2x = sin^-1(0.156)
----
2x = 0.1566 radians
x = 0.0783 radians
