#### Class 12 Maths Exercise 8.2 Solution in Videos

##### Area under the conic section

In this subsection, we will find the area of a line bounded by a line and a circle, a line and a parabola, a line and an ellipse. Curve equations will be in their standard forms only if matters in other form are beyond the scope of NCERT books for class 12 mathematics for the session 2022-2023. From the examples of the bounded area, it follows that we can consider vertical stripes or horizontal strips to calculate the area of the sphere. From now on, we will consider either of these, preferably vertical bars. It seems more convenient to judge which area is to be counted.

###### Area between the two curves

Deeply true in Leibnitz’s sense, integration is the act of calculating the region by cutting it into small strips of a large number of smaller regions and then adding these fundamental fields. Suppose we have y = f (x), y = g (x), where f (x)> g (x) are two curves represented by [[, b]. Here, the intersection points of these two curves are given by x = a and x = b, taking the normal values of y from the given equation of the two curves. To establish a formula for the integral, it is convenient (as we discussed above) to take the primary field as vertical stripes. As indicated in the primary bar, it has height f (x) – g (x) and width dx hence the primary area.
