Students can go through the description of each chapter to get an overview of the contents of the chapters. The chapter-wise description has been included in the following sections. The sub-topics in this chapter are listed below:. Download Answers PDF. In this chapter, you will study the restrictions on domains and ranges of trigonometric functions that ensure the existence of their inverses and observe their behavior through graphical representations.

Besides, some elementary properties will also be discussed. The inverse trigonometric functions play an important role in calculus for they serve to define many integrals. The concepts of inverse trigonometric functions are used in science and engineering.

The determinant is a scalar value that can be measured from the elements of a square matrix and encodes certain properties of the linear transformation described by the matrix. The determinant of a matrix A is denoted det A , det A , or A. In this chapter, we will learn everything about Continuity and Differentiability of a function. You will also learn the differentiation of inverse trigonometric functions.

Further, this chapter introduces a new class of functions called exponential and logarithmic functions. In this chapter, you will study applications of the derivative in various disciplines, e. You will also use the derivative to find intervals on which a function is increasing or decreasing.

Differential Calculus is centered on the concept of the derivative. Integral Calculus is motivated by the problem of defining and calculating the area of the region bounded by the graph of the functions. Here, in this chapter, you will study a specific application of integrals, to find the area under simple curves, area between lines and arcs of circles, parabola, and ellipses standard forms only.

We shall also deal with finding the area bounded by the above-said curves. In this chapter, we will study some basic concepts related to the differential equation, general and particular solutions of a differential equation, formation of differential equations, some methods to solve a first-order — first-degree differential equation, and some applications of differential equations in different areas.

In this chapter, we will study some of the basic concepts about vectors, various operations on vectors, and their algebraic and geometric properties. These two types of properties, when considered together give a full realization to the concept of vectors and lead to their vital applicability in various areas.

In this chapter, we shall study the direction cosines and direction ratios of a line joining two points and also discuss the equations of lines and planes in space under different conditions, the angle between two lines, two planes, a line and a plane, the shortest distance between two skew lines and distance of a point from a plane.

Most of the above results are obtained in vector form. Also, we shall study some linear programming problems and their solutions by graphical method only, though there are many other methods to solve such problems. We shall also learn an important concept of a random variable, its probability distribution, and also the mean and variance of a probability distribution.

Show that f is invertible. Find the inverse. A circular disc of radius 4 cm is being heated. Due to expansion, its radius increases at a rate of 0. Find the rate at which its area is increasing if the radius is 5. There are 5 cards numbered 1 to 5 with one number on each card.

Two cards are drawn at random without replacement. If both of them try to solve the problem independently, then calculate the probability that the problem is solved. Unit 1: Relations and Functions 1. Relations and Functions — Composite functions, inverse of a function. Applications of Derivatives — Rate of change of bodies, use of derivatives in approximation 4.

Let A and B be two sets. Types of Relations. Let f be a function from A to B. If every element of the set B is the image of at least one element of the set A i.

*Question 9. Find the set of all elements related to 1 in each case.*

И направился в сторону люка. - Коммандер. Хейл очень опасен. Он… Но Стратмор растворился в темноте. Сьюзан поспешила за ним, пытаясь увидеть его силуэт.

Он прикрыл микрофон телефона рукой и гневно посмотрел на своего молодого сотрудника. - Мистер Чатрукьян, - буквально прорычал он, - дискуссия закончена. Вы должны немедленно покинуть шифровалку. Немедленно. Это приказ. Чатрукьян замер от неожиданности.

ГЛАВА 110 Невидящими глазами Джабба смотрел на распечатку, которую ему вручила Соши. Он побледнел и вытер рукавом пот со лба. - Директор, у нас нет выбора. Мы должны вырубить питание главного банка данных. - Это невозможно, - сказал директор.

Даже те, кто использовал электронную почту лишь для развлечения, занервничали из-за вторжения в их частную жизнь. Корпоративные программисты во всем мире озаботились решением проблемы безопасности электронной почты. В конце концов оно было найдено - так родился доступный широкой публике способ кодирования.

*Он знал, что этого времени у него. Сзади его нагоняло такси. Он смотрел на приближающиеся огни центра города и молил Бога, чтобы он дал ему добраться туда живым.*

Они бежали за уже движущимся автобусом, крича и размахивая руками. Водитель, наверное, снял ногу с педали газа, рев двигателя поутих, и молодые люди поравнялись с автобусом. Шедший сзади, метрах в десяти, Беккер смотрел на них, не веря своим глазам. Фотография внезапно обрела резкость, но он понимал, что увиденное слишком невероятно. Один шанс к миллиону.

* Надо вырубить все электроснабжение, и как можно скорее! - потребовала Сьюзан. Она знала, что, если они не будут терять времени, им удастся спасти эту великую дешифровальную машину параллельной обработки. Каждый компьютер в мире, от обычных ПК, продающихся в магазинах торговой сети Радиошэк, и до систем спутникового управления и контроля НАСА, имеет встроенное страховочное приспособление как раз на случай таких ситуаций, называемое отключение из розетки.*

A good score in this class is equivalent to quality high education.
