Graphical Representation of Uniform Motion
Position-time graph for uniform motion - The rate of change of position of a particle in a particular direction gives the velocity of the particle. It may also be defined as the time rate of change of displacement of a particle. Velocity is a vector quantity. A motion is said to be uniform if the p..

A real number line can be used to represent the solution set of an inequation (Linear). The convention is that O (a hollow circle) marks the end of a range with a strict inequality (i.e. < or >) and (a darkened circle) marks the end of a range involving equality as well as inequa..

> If the scales selected for the representation of three vectors are the same, then, three equal vectors are represented by three arrows of equal lengths, pointing in the same direction. If, however, the scales chosen are different, then, it is possible to represent ..
Wave number
It is the number of wavelengths per centimeter. It is equal to the inverse of a wavelength expressed in centimeter. The relationship that follows between wavelength, frequency and velocity is, velocity = wavelength x frequency c = l x ..

In this type of hybridisation one '2s' and one '2p x ' orbitals get hybridised to form two equivalent orbitals called 'sp' hybrid orbitals. The remaining 2p y and 2p z do not take part in hybridisation. The two unhybridised orbitals are directed along the 'y' and 'z' axes while the two hybridise..

Frequency Distribution - A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an array. The dif..

Linear Inequations - A statement is an assertion or a sentence that is either true or false, but not both. A variable is a symbol that may represent any member of a specified set called replacement set or domain of that variable. A mathematical expression is a symbolic representation for ..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
Very good, Tutor was clear and guided me through the whole algebra problems
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
