WebNov 16, 2024 · The intersection of each of the first two spheres with the earth's surface is a circle, which defines two planes. The mutual intersections of all three spheres therefore lies on the intersection of … WebMar 24, 2024 · The line on Earth where one calendar day becomes the next is known as the International Date Line (IDL) which passes through the Pacific Ocean. The line is generally found 180 degrees from the Prime Meridian but the line circumvents some regions and islands to avoid dividing contiguous pieces of regions and countries into two …
geometry - Determining circle-line intersection on sphere
WebNov 27, 2024 · Well, speaking of degrees, the very first circles of latitude start from the equator which is at 0 degrees. Later, from the equator, these circles expand to the north and south poles of the earth. Both the north pole and south pole are at … A line can intersect a circle in three possible ways, as shown below: 1. We obtain two points of the intersection if a line intersects or cuts through the circle, as shown in the diagram below. We can see that in the above figure, the line meets the circle at two points. This line is called the secant to the circle. 2. If we draw … See more There are two methods to think about this. Method 1: Let us consider the equation of the circle be \({x^2} + {y^2} = {a^2}.\) And that of the line be \(y = mx + c.\) First, if we want to solve the two … See more Q.1. Prove that the line \(y = x + 4\) intersects the circle \({x^2} + {y^2} + 8x + 2y – 84 = 0.\) Ans: We are given a linear equation \(y=x+4.\) The equation of a circle is \({x^2} + {y^2} + 8x + 2y – 84 = 0.\) Substitute \(y = x + … See more Q.1. What does it mean for a line to intersect a circle at one point? Ans:If a line intersects a circle at only one point, that line will be a tangent … See more In this article, we have discussed line and circle and their general forms. Then we saw the three cases of the intersection of a circle and a line.
