Define dimension and a basis of a vector space |
|
Answer» In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the MINIMUM number of coordinates needed to specify any point within it.[1][2] Thus a line has a dimension of ONE because only one COORDINATE is needed to specify a point on it – for example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it – for example, both a latitudeand longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is THREE-dimensional because three coordinates are needed to locate a point within these spaces. |

Use euclids division lemma to show that the square of any poistive integer is of the form 3p. ,3p+1 |
|
Answer» LET US take, 'X'= 3q , 3q+1, 3q+2 when, x=3q x2 = (3q) 2 x2 = 9q2 x2 = 3(3q2) we see that 3q2= m so we have done the first equation 3m when , x=3q+1 x2= (3q+1)2 [since, (a+b)2 = a2+2ab+b2] x2= 9q+6q+1 x2= 3(3q+2q)+1 in this we see that 3q+2q= m THEREFORE, this SATISFY the equation m+1 |

According to normalization rules a table is said to be in second normal form if and only if it is |
| Answer» In a table, if attribute B is functionally dependent on A, but is not functionally dependent on a proper SUBSET of A, then B is considered fully functional dependent on A. Hence, in a 2NF table, all non-key attributes cannot be dependent on a subset of the primary key. Note that if the primary key is not a composite key, all non-key attributes are always fully functional dependent on the primary key. A table that is in 1st normal FORM and CONTAINS only a single key as the primary key is automatically in 2nd normal form. | |
