Polarization
Light is an electromagnetic wave with electric and magnetic field vectors varying sinusoidally, perpendicular to each other as well as perpendicular to the direction of propagation of wave of ligh..
Polarity of water molecule
Oxygen is more electronegative than hydrogen, being only second to fluorine in its electronegativity. Its high electronegativity causes the oxygen atom to pull the shared pairs of electrons more towards itself. As a result, the O-H bond acquires polarity. Since the two O-H bonds in water..
Graphs of Polar-Coordinate Equations
- So far we have learnt how to graph a point with polar coordinates (r, θ). Now lets see graphing polar equations. We know the polar coordinate system is similar to rectangular coordinate system. In a polar coordinate field, there will be a series of ci..

Angle
When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle at A, the..

Definition - When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m AOB. An h..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
I really liked this sessions becuse i am able to understand some problems that i didn't originally understand. This sessions was a great oppurtiunity for me to learn. I really enjoy being with tutorvista!!!!!!!!!
Tutor Vista's White board is a great tool which is having all the varieties of lines for my geometry. It's a great design...Peter
