# Number of images formed by two mirrors formula

The hyperbolic tangent function is an old mathematical function. It was first used in the work by L'Abbe Sauri (1774). This function is easily defined as the ratio between the hyperbolic sine and the cosine functions (or expanded, as the ratio of the half‐difference and half‐sum of two exponential functions in the points and ):

Sol. (a) Only one image will be formed rays after reflection converge at same position. (b) Object distance = image distance for plane mirror so image is at (4, 0). (c) Ray OP does not strike the mirros so it does not take part in image formation. 8.

length(x) is the number of elements in x, sum(x) gives the total of the elements in x, and prod(x) their product. Two statistical functions are mean(x) which calculates the sample mean, which is the same as sum(x)/length(x), and var(x) which gives There are two objects equal in mass and size and shape... identical blocks of wood for example. They are on a horizontal plane with no friction. The first object moves at 10 mph and collides with the second which is at rest. The two masses merge together (unlike billiard balls,where one stops and the other moves on), and continue as one mass. PARALLAX CORRECTIVE METHODS (Optics Design) I. REAR (SECOND FOCAL PLANE TYPE) CORRECTIVE ADJUSTMENTS. This feature is usually a numbered range ring from minimum yardage (usually 50) to maximum yardage (usually infinity) and sets directly in front of the eyepiece, similar to the usual variable power ring but controls the Parallax Adjustment.

A correlation is a single number that describes the degree of relationship between two variables. Let's work through an example to show you how this statistic is computed. Correlation Example. Let's assume that we want to look at the relationship between two variables, height (in inches) and self esteem. The purpose of this essay is to explore the area formed by the intersection of overlapping circles and how it is affected by the distance between their centers. Lets begin with two circles with the same radius, r, overlapping each other (see figure below) and we want to find what is the area of the overlapped section (i.e., green area). CHEM 120 Online: Chapter 6 Sample problems Date: _____ 1. To determine the formula mass of a compound you should A) add up the atomic masses of all the atoms present. B) add up the atomic masses of all the atoms present and divide by the number of atoms present. C) add up the atomic numbers of all the atoms present. is moved with the help of the fine movement screw and the number of fringes that cross the field of view is counted. The wavelength is determined from the fact that for one fringe shift, the mirror moves through a distance equal to half the wavelength. Nature of fringes: If the two mirrors M 1 and M 2
