However, to find the distance along a circle of latitude
, one needs to know the radius of that small circle, which can be derived from Figure 4.
Their mine was about 500 miles north of Santiago, south of this major circle of latitude
His latest book, Tropic of Capricorn, covers his adventures travelling along this southern circle of latitude
This can be depicted as an evolution along a circle of latitude
on the Bloch sphere with periodicity of 2[pi].
In Figure 5, we show the circle of latitude
[[theta].sub.L] with the sun's rays impinging on it when the earth's position is specified by the angle [alpha], and we indicate the two points S and T where the plane y = sin 0.833 intersects with this circle.
Scientists will tell you the 55th parallel north is a circle of latitude
that is 55 degrees north of the Earth's equatorial plane.
Then, with considerable patience (and flexible cardboard!), manoeuvre circle c so as to represent the circle of latitude
at 30 degrees south by sliding together slots B and also slots E.
