As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...

Any point P with coordinates (\(x, y\)) on the circumference of a circle can be joined to the centre (0, 0) by a straight line that forms the hypotenuse of a right angle triangle with sides of length ...

Here, we are providing you the important concepts, formulae and some previous years solved questions related to Circle for JEE Main and JEE Advanced 2019. About 1-2 questions are being asked in the ...
