It's 1/2 of sin(2 theta) .

2 sin^2 theta = 1/4 sin^2 theta = 1/8 sin theta = sqrt(1/8) theta = arcsin(sqrt(1/8))

It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!

Sin theta of 30 degrees is1/2

It's possible

because sin(2x) = 2sin(x)cos(x)

4 sin(theta) = 2 => sin(theta) = 2/4 = 0.5. Therefore theta = 30 + k*360 degrees or 150 + k*360 degrees where k is any integer.

[]=theta 1. sin[]=0.5sin[] Subtract 0.5sin[] from both sides.2. 0.5sin[]=0. Divide both sides by 0.5.3. Sin[] =0.[]=0 or pi (radians)

If sin (theta) is 3/5, then sin2 (theta) is (3/5)2, or 9/25.

Since theta is in the second quadrant, sin(theta) is positive. sin2(theta) = 1 - cos2(theta) = 0.803 So sin(theta) = +sqrt(0.803) = 0.896.

2 sin (Î˜) + 1 = 0sin (Î˜) = -1/2Î˜ = 210Â°Î˜ = 330Â°

It is a mathematical expression.
