definition of assignment problems

Simultaneous Equations - A linear equations in two variables x and y is of the form ax + by + c = 0 ( ) where a, b, c are real numbers. To find a solution for this equation, we can assign any value for one of the variables and find the value of the other variable such that the two sides o..

Lens Formula - The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula or lens equation. -------- Lens formula This lens formula is applicable to both convex and concave lenses. Note: Points to be remembered while using ..

In the first quadrant, as x approaches zero from the right of zero, the value of f(x) increases without bound. It becomes greater than any assigned positive real value. In this case, we say or Similarly, in the third quadrant as x approaches zero from the left, the value of decre..

An atom is a very minute particle and so the actual mass of an atom is extremely small. It is physically not possible to measure such small masses easily. In 1811, Avogadro suggested that atomic and molecular masses can be expressed on an atomic mass scale relative to that of a standard reference ..

In propane a torsional barrier results in slightly hindered rotation about the carbon-carbon bonds. In the eclipsed conformer there are two ethane type Hydrogen-hydrogen interactions and one additional interaction between a carbon hydrogen bond and a carbon-carbon bond. A slightly higher barrier t..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number, X( w i ) = x i is called a random variable . Two types of random variables are 1. Continuous random variable, 2. discrete ra..

Geometry is an interesting area of Math that requires a proper understanding of the basics. The fundamentals of Triangles, rectangles and rectilinear figures need to be properly taught in order to understand higher concepts. Learn Geometry online with TutorVista's team of highly qualified and expe..

. Hydrocarbons are a parent group of carbon compounds with many sub functional groups. Carbon compounds are known to exist as linear chains, branched chains and cyclic rings Nomenclature is the system of assigning a proper name to a particular organic compound on the basis of certain rule..

. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated with a definite amount of energy given by his mass-energy ..
