solution set for an equation

The equation x 2 + 143 = 43 has a solution in which set of numbers? => Integers or Irrational numbers or Complex numbers or Natural numbers..

The set of ordered pairs (x,y), which satisfy the given inequation, is called the solution set of the inequation..

The statement A B that every element of A is also in the set B, which includes the possibility that A = B. The statement A B (A is a proper subset of B) that A is a subset of B and A B; hence there exists at least one element in B which is not in A. ..

For the preparation of lyophilic and lyophobic sols different methods are us..

Purification of Colloidal Sols - The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols. Impurities are removed by the following methods: 1) D..

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Lyophobic sols are prepared by two methods. They are: 1) Condensation methods 2) Dispersion method..

The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols. Impurities are removed by the following methods: 1) Dialysis 2) Ultra-filtration 3) Ultra-Centri..

A set of values of the variables x 1 , x 2 , x 3 ,.,x n which satisfy all the constraints and also the non-negativity conditions is called the feasible solution of the LP..

Figure shows the set up. O is the central bright fringe. D 1 and D 2 are the first dark fringe on either side of central maxima. Obviously Given = 6.5 x 10 - 7 m: D = 1.8m, d = 5 x 10m The distance between D 1 and D l 1 = 2x = 4.6..
