linear relation between two quantities

Suppose X = ab Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be the maximum possible error in X. Dividing both sides by X = ab, we get are relative errors of fractional errors in values of a, b and x. Neglecting a..

The development of chemistry is based upon the systematic approach of the scientists in carrying out different experiments. Scientific theories, inferences and generalizations are made on the observations recorded. The quantitative information involves the measurement of one or more quantities..

Linear equations in two variables - A Linear equation is a first degree algebraic expression with one,two or more variables equated to a constant. Graphically a linear equation with one or two variables is a straight line whereas one with ..

Relatives - The words who, which, where and whose are called relatives which give us information about a person or thing and help us to convey two-different ideas in a well-connected wa..

If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b..

If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b. Let R mean 'is greater than', then xRy mea..

= maximum percentage error in a + maximum percentage in b. From equations 3, 4, 5 and 6, it is seen that when the result involves the multiplication or quotient of 2 observed quantities, the maximum possible relative error in the result is equal to the sum of the ..

The quantity to be maximized or minimized is represented by a linear function called ______. => The restriction or The constraint or The feasible function or The objective function..

Assume a rod of material having a length L o at initial temperature T o . When the temperature changes by D T, the length changes by D L. Experiment shows that if D T is not too large (say, less than 100 o C or so), D L is directly proportional to D T. If two rods made of the same materia..
