Explanation Given: The region bounded by the graphs of y = sin x 2 , y = cos x 2 , x = 0 and x = π 2 Formula used: We will use the Shell Method Calculation: We are given with the region bounded by the curves y = sin x 2 , y = cos x 2 , x = 0 and x = π 2 . First consider the graph of sin x and cos x , then it can be seen that sin x 2 and cos x 2 are even function. Now, find the intersection point of sin x 2 and cos x 2 . For this, sin x 2 = cos x 2 x 2 = π 4 x = π 2 Negative value of x is not taken because required region lies in the first quadrant. Hence, the sin x 2 and cos x 2 intersects at the point, ( π 2 , 2 2 ) . We get the required region is given by, Now, the bounded region is revolved around the y -axis then the solid obtained is, Now, Useshell method, the required volume is V = 2 π ∫ a b p ( x ) h ( x ) d x Where, p ( x ) radius of the cylinder is h ( x ) is height of the cylinder

Optimization

Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the se…

Integration

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integratio…

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
