Polar Equation of Lines
Simple line equation in terms of polar coordinates. Let us consider the form Ax + By = C as a standard equation of a line in the x y plane. Transformation with coordinate will be x = r Cos θ and y = r Sin θ . Then the equation becomes, r(A cos θ + B sin &t..
Resultant velocity of a horizontal projectile:
In this section, let us calculate the resultant velocity of the projectile , at any point p on the trajectory, in an interval of time t. V x and V y are the horizontal and vertical components of as illustrated in the figure below. ..

The direction of the magnetic field due to a current may be studied by drawing the magnetic lines of force. A vertical wire AB is passed through a horizontal cardboard PQRS. Ion filings are sprinkled on the cardboard. Current is passed through it by connecting a battery to it. I..

Some examples of horizontal circular motion are planetary motion (which may or may not be circular), merry-go-round and motion of electrons around the nucleus. There is one thing that is common in all these cases. The particle's acceleration is always directed towards the centre..

Work is done in displacing a body with constant velocity. For e.g., your mother asks you to shift an almirah by pushing it to the other room. You may feel tired after pushing it. But if she now says that the third room is more suitable and you push it to the third room you feel more tired than befo..

Very Very Very Fabulous tutor She is the BEST!! tutor I have met in tutorvista for ENGLISH. KEEP IT UP GOOD WORK WOW!! Thankyou
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.
Really good tutors. Real helpful and made things easy to understand. Tutor vista is a real online tutoring company
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
