How to Become Well-Versed With the Concept of the Equation of a Circle?

Equation of a Circle

The circle is considered to be a figure that has been obtained by joining all the points into a plane that will be at an equal distance from the point of the centre. The radius of the circle will be the distance between the centre and any point on the boundary of the circle and it is very much important for the kids to be clear about this particular concept. Apart from this drawing out the circle on a graph is also very much important for the kids so that they can become very much successful in terms of solving different kinds of complex questions without any kind of problem. The standard form of the equation of a circle has been explained as follows:

X minus X1 whole square plus Y minus Y1 whole square is equal to radius Square

It is also very much important for the kids to be clear about the basic terms like the centre of the circle or centre at origin because the implementation of this particular formula will also come out to be a comprehensive equation that has been explained as follows, The kids need to get enrolled on platforms like Cuemath so that they can get clear about the concept of the equation of the circles and the equation of a line.

X square plus Y Square is equal to radius Square

It is important to be clear about the concept of Centre on X-axis because in this way the equation will further differ and has been explained as follows:

X minus A whole square plus Y Square is equal to radius Square

In the cases of centre on the Y-axis it is also very much important for the people to be clear about this concept because it will further come with a comprehensive equation which is explained as follows:

X square plus Y minus B whole square is equal to radius Square

In the cases of the circle touching the X-axis the equation will come out to be:

X minus A whole square plus Y minus R whole square is equal to radius square

In the cases of the circle touching the Y-axis the equation will differ and come out to me:

X minus R whole square plus Y minus B whole square is equal to the radius Square

When the circle is touching the X and Y axis then the equation will come out to be:

X minus R whole square plus Y minus R whole square is equal to radius Square

Following are the basic tips to be followed in the whole process:

  1. If the circle is touching both the axis then the people need to consider the centre of the circle to be R, R where R will be the radius of the circle.
  2. This can be both negative as well as positive and the best benefit is that it will always help in making sure that plotting of the coordinates on the graph will become very easy.
  3. If the tangent is touching the circle at any point then the point of contact of the tangent will satisfy the equation of the circle as well as the equation of the tangent perfectly.

Apart from this it is also very much important for the kids to be clear about the conversion of the standard form to be general form and the general form has been explained as follows:

X square plus Y Square plus AX plus BY plus C is equal to 0

In this case A, B and C will be constants

They will be taught here by the experts and they will make sure that everything will be done in the best possible manner. It is relatively easy to move with experts who make sure that people will be able to fetch good marks in the exams. With the help of online classes and doubt sessions, it becomes easy to solve things.
