Vitamin D is the collective term for a group of fat-soluble compounds, which occur in two major forms: ergocalciferol or vitamin D2, and cholecalciferol or vitamin D3.
This supplement contains vitamins C, D2, E, B1, B2, B3, B6, B12, folic acid, iodine, zinc, copper and magnesium, along with PABA, Fenugreek, Aloe Vera and silica.
To operate with D2 upon (213) (214) (15), we have D (2)f = (13) (214) (15) + (213) (14) (15), D c1 2)f = (122) (213) (15) +(213) (213) (14) + (212) (214) (14), and hence D2f = (214) (15) (13) +(213) (15) (14) +(213) (212) (15) +(213)2(14) +(214) (212) (14).
If a is the distance shown by the normal triplets the type of separation observed in the line D2 shows distances from the central line equal to a /3, 3a/3, 5a/3, while the type of D 1 gives 2a/3, 4a/3.
Then, since Hp, the force at M due to m and - m, is the resultant of d, and - m2, we have (L Hp m d d2 2ml H = d3, the direction being parallel to AB.
If in the identity f =f l f 2 ...fm we introduce a new root A we change a 8 into a8+/la8_l, and we obtain (1 +AD1 2 D2+...
3 tan 8, d l - I _ idlv j d23 d2/ I - 1d12H tan ©.
We then have approximately for the field at M due to the rod 4 HP= (dm1)2 (d + 1) = m (d 2 _ M Therefore 2m1= = (d2 - 12)2Ht, - (d2-12)2HEtan 0 2d 2d (44) M (d2-12)2HE (45) And I = v - 2dv tan 0, whence we can find the values of I which correspond to different angles of deflection.
The logarithm is then obtained by use of the formula d l d2 l d3 2 log e (x+d) = log e x-f- - x2+3 x3 - &c., in which of course the object is to render dlx as small as possible.
It is clear that direct transmission through the plate at a point where the thicknesses of the prisms are d 1 and d 2 will introduce a relative retardation of (µ,; -, u o) (d l - d2) between streams polarized in planes parallel and perpendicular to the edges of the prisms,, u o, and being the ordinary and the extraordinary refractive indices; and it is hence possible by an adjustment of the thickness to reduce elliptically polarized to plane polarization at an assigned point marked off by two parallel lines.
