Similarly, binary operation refers to two elements of a set. The result of the two is also in the same set. Finally, binary operation refers to the calculation that combines the two elements of the set (known as operands) to produce another element for the same set.

Chapter 12 Higher order derivatives teach us how to find the derivative of a function using differentiation. We can obtain the second-order derivative of a function with the proper understanding of the higher-order derivative. The concepts taught in this chapter will be frequently used in physics derivatives. Integration constitutes the core of these mathematical concepts.
Chapter 13 Derivative as a rate measure will introduce you to the practical Application of Derivatives that will further be applied to find the radius of a cube, calculate the value of the hub, etc. The applications of derivatives at times are helpful in measuring the rate of change.

This chapter deals with an in-depth knowledge of the Differential error and approximation method. The basic concept of Chapter 14 Differentials, Errors, and Approximations revolves around taking in differential functions as a function of x. We then assume delta x and delta y as small changes in the variable X and Y, respectively, and can also be called the differential of Y.
This chapter deals with the definition and the graphical representation of the mean value theorem. It says that for any given curve between two ends, there exists a point at which the slope of the tangent to the curve is equivalent to the slope of the second through its endpoints.

This chapter is considered the most scoring topic of class 12 Math. We study the basic concept of the equations of a tangent and a normal to the general curves. Chapter 16 Tangents and normal also gives the basics graphs and the basic concept of coordinate geometry. It is used to find the nature of the angle of intersection of two curves and includes the equations required to find the length of the tangent, normal, sub-tangent and subnormal.
In this chapter, we can determine whether a function is increasing or decreasing in a particular interval. We can figure out if the function is increasing through graphical representations, and we can find an upward (increasing) pattern. A downward pattern is exhibited in a decreasing function, and an increasing function is categorized by an increase in the value on the y-axis with this increase. The decreasing function can also be identified as the value of Y decreases with an increase in the value of X.
Chapter 18 Maxima and Minima deal with the properties of Maxima and minima. In this chapter, the maxima and minima of a function have collectively termed the extrema for the largest and smallest value of a function within the given range. For example, a function may have several local Maxima and a local minimum in a given interval. We need to find the local Maxima or local minimum value. This chapter covers three methods to find the local extrema: the first derivative test, the second derivative test, and the N th derivative test.
Chapter 19 Indefinite Integrals deal with the concept of derivatives. In this chapter, we will only be finding the anti-derivative of functions. The three methods to integrate a given function include the integration by substitution method, integration by parts method, and integrating relational algebraic functions using partial fractions.

Chapter 21 - Area of bounded regions aims to find the area made up of line segments, circles, semicircles, cones, cylinders, etc., such that they form a geometric figure. There are some questions in which we cannot form the entire shape by joining the smaller components of the area bounded. Here the application part of integral comes into play by making it easier for us to calculate the area enclosed by the curves. It tells us about both regular and irregular shapes. These can be made by drawing vertical and horizontal stripes. The area enclosed in the two curves can be calculated using the same method.

This chapter describes the process to find a scalar triple product in an easy-to-understand manner.

Straight lines can also be categorized as zero-width objects that extend in opposite directions without any ends.
Chapter 29 - The Plane discusses a flat two-dimensional surface characterized by an infinite dimension and no thickness. A plane in 3-D space can be correctly represented by an equation with three variables, a, b and c, that must be non-zero.
