Step-by-step explanation:
The answer is B because bias is basically something or someone that you favor over anything or anyone else. Or what you belving in your own opion.
As an example, our strong bias in favor for the idea, or a test biased towards people who are excellent at math.
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
2sin(x)cos(x) - cos(x) = 0
so one solution is cos(x) = 0.
=> x = pi/2 and 3pi/2 (90° and 270°)
for cos(x) <> 0 we have then
2sin(x) - 1 = 0
2sin(x) = 1
sin(x) = 1/2
=> x = pi/6 and 5pi/6 (30° and 150°)
