rules on signed integers

What should be the sign of the integers, if the product of the two integers is positive? => Either both the integers should be positive or both negative. or Multiplier is positive and multiplicand is negative. or Multiplier is negative and multiplicand is pos..

The emf of a cell is positive when one moves in the direction of increasing potential (i.e., negative pole to positive pole) through the cell and is negative when one moves from positive to negativ..

Sign Conventions and Rules for Drawing Ray Diagrams - These new cartesian sign conventions adopted during measurements are as follow..

. Thus, height of an object and that of an erect image are positive and all distances measured below the principal axis are negative. Note: The rules are same as in case of spherical mirrors. The following table gives the sign convention for lenses: Types of lens U v f Height of..

Aromaticity (Huckel rule) - Aromatic compounds are those, which resemble benzene in chemical behavior. These compounds contain alternate double and single bonds in a cyclic structure. They undergo substitution reactions rather than addition reactions. This characteristic behavior is calle..

(1) Let the given function be f (x) on the real number line R. (2) Differentiate the function f(x) with respect to x and equate it to zero i.e., put f '(x) = 0. Solve for x. These values of x which satisfy f '(x) = 0 are called Critical values of the function (3) Arrange these Critical values in a..
