Heisenberg uncertainty principle states that it is impossible to determine the exact position and the exact momentum of the particle simultaneously.

According to Heisenberg uncertainty principle, Δx.Δp≥ h/4π. Thus lesser the error in the momentum, more will be the error in the position of the particle.

The reference angle is the smallest angle between the terminal side and the x-axis.

$(1)\ \theta = 300^o$

300 degrees is in the 4th quadrant.

So, the reference angle is

$\alpha = 360 - \theta$

$\alpha = 360 - 300$

$\alpha = 60^o$

Hence, the reference angle of 300 degrees is 60 degrees

$(2)\ \theta = 225^o$

225 degrees is in the 3rd quadrant.

So, the reference angle is

$\alpha = \theta - 180$

$\alpha = 225 - 180$

$\alpha = 45^o$

Hence, the reference angle of 225 degrees is 45 degrees

$(3)\ \theta = 480^o$

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 120$

$\alpha = 60^o$

Hence, the reference angle of 480 degrees is 60 degrees

$(2)\ \theta = -210^o$

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 150$

$\alpha = 30^o$

Hence, the reference angle of -210 degrees is 30 degrees

Answer:

4pi/3

Explanation:

XY = YZ = XZ = 2

angle YXZ is pi/3

wxy is 2pi/3

Area of the circle = pi*r^2 = 4pi

Area of the shaded area = 4pi * (2pi/3)/(2pi) = 4pi/3
