In this they were completely successful, for they obtained general solutions for the equations ax by = c,

**xy**= ax+by+c (since rediscovered by Leonhard Euler) and cy 2 = ax e + b.When the plane zx is not a plane of symmetry, we have to consider the terms in

**xy**, 2 y, and y 3 .If the direction of motion makes an angle 0' with Ox, tan B' = d0 !dam _ ?

**xy**2 = tan 20, 0 =-10', (9) dy/ y and the velocity is Ua2/r2.There is, however, considerable evidence in support of the view that Greek va representing the sound arising from Ky,

**xy**, Ty, By was pronounced as sh (s), while representing gy, dy was pronounced in some districts zh (z).4 On an inscription of Halicarnassus, a town which stood in ancient Carian territory, the sound of vv in `AXoKapvaao-Ewv is represented by T, as it is also in the Carian name Panyassis (IIavvfiTcos, geni tive), though the ordinary is also found in the same inscription.The cartesian equation, if A be taken as origin and AB (= 2a) for the axis of x, is

**xy**2 =4a2(2a - x).AdvertisementStating the theorem in regard to a conic, we have a real point P (called the pole) and a real line

**XY**(called the polar), the line joining the two (real or imaginary) points of contact of the (real or imaginary) tangents drawn from the point to the conic; and the theorem is that when the point describes a line the line passes through a point, this line and point being polar and pole to each other.By taking this plane, which is that of the orbit in which the planet performs its revolution, as the plane of

**xy**, we have only two co-ordinates to consider.In all such cases, there is no component to plan convexity, any curvature being entirely orthogonal to the

**xy**plane.In some South American field mice and the Scandinavian wood lemming,

**XY**females are commonplace.Rather than columns running along a 2D x axis, a city scape consists of square columns at

**xy**locations.AdvertisementFor the simple case of a tensile stress sigma x combined with a shear stress tau

**xy**.Females have two X chromosomes (the XX combination); males have one X and one Y chromosome (the

**XY**combination).This means that rather than having the normal

**XY**combination, the male has an XXY combination.Males have one X and one Y chromosome (

**XY**).Since the egg has no gender, it's the sperm's job to combine either a Y or X chromosome with egg's X chromosome to produce a boy (

**XY**) or a girl (XX).AdvertisementIf the sperm that fertilizes the egg is Y, then the baby will be
