Relative Atomic Mass
An atom or a molecule is a very minute particle; the actual mass of an atom is extremely small. The mass of atoms extends from 1.67 x 10 - 2 4 g (hydrogen) to 4.0 x 10 - 2 2 g only. It is physically not possible to measure such small and light masses easily. In 1811, Avagadro suggested ..

Over the set of numbers R, which of the following is true for the function f ( x ) = ln ( x 2 + 8)? => f ( x ) has relative maximum at x = 0 or f ( x ) is increasing at x = 0 or f ( x ) has no extreme val..

The set of first elements in a relation is called Domain. In example (6), Domain is set A = {1, 2, ..
Function
We consider two sets A and B. We form the Cartesian Product, we form relations. From all the relations, we can select a few which satisfy the rule that each element of the set A is related to only one element of the set B. When a re..
Reflexive property
A relation R in a set A is said to be reflexive if every element of the set A is related to itself. This is if aRa where a A, or (a, a) R for each a A For example, (i) a triangle 'is congruent to' itself. (ii) 5 is a multiple of'..
Alternate Definition:
Difference of two sets A and B, A - B is a set whose elements belong to A but not to B. A - B is called the relative complement of B w.r.t. ..

I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
This tutoring is AWESOME. i would have never gotten such a complicated word problem with their help. Terrific job....well done.... - Bob
Tutor is Very patient with me and attentive towards my needs. The best tutor and session I have experienced. Keep up your possitive spirit.
This site has a chatbox and whiteboard workspace for students like me where i can write or draw problems, get solutions and explanations, and I can also see animations to understand better.
