In this article the energy eigenvalues and eigenfunctions of such an atom in three different situations of confinement inside (a) a circle (0 ≤ρ≤ρ0, 0 ≤φ≤ 2π), (b) an angle (0 ≤ρ≤∞, 0 ≤φ≤φ0), and (c) a circular sector (0 ≤ρ≤ρ0, 0 ≤φ≤φ0) are ...
Opposite Angles in a Cyclic QuadrilateralA cyclic quadrilateral is a quadrilateral whose vertices lie on a circle and it is also known as a quadrilateral inscribed in a circle. In other words, it is a quadrilateral that is inside a circle and all its vertices touch the circle. There are ...
If you've ever seen a birth chart, you would have noticed that all of the planets are scattered inside of a circle that's divided into 12 pie slices, conveniently called "houses." Houses are important because, without them, astrologers have no way of bringing the significance of cosmic eve...
Learn about arcs and angles in a circle. Learn how to find angles in a circle, and see how the formulas change when angles are inside or outside the circle. Related to this QuestionSolve for x. The given angles are 60 degrees and 20 degrees. Solve for x. The given angle is 4...
A point is selected at random inside an equilateral triangle. From this point perpendiculars ()are dropped to each side. The sum of these perpendiculars is ( ).(A)Least when the point is the center of the triangle(B) Greater than the altitude of the triangle(C) Equal to the altitude ...
Let A, B, C, and \(C'\) be four points of a circle \(\mathcal {K}\), where line \(CC'\) lies on another fixed (finite or infinite) point F. Then the locus of two diagonal points (not on line \(CC'\)) of cyclic quadrilateral \(ABCC'\) is a conic if C is moving al...
In this quick maths article, find out what the angles in a polygon add up to, as well as the difference between interior and exterior angles.
Theorem: The measure of the angle formed by 2 chords that intersect inside the circle is 12 the sum of the chords' intercepted arcs. Diagram 1 In diagram 1, the x is half the sum of the measure of the intercepted arcs (⏜ABC and ⏜DFG) Note: This theorem applies to the ang...
