Step 2: Now, to obtain the second term of the quotient, divide the highest degree term of the new dividend by the highest degree term of the divisor. Again, carry out the division process. Step 3: Now, the degree of the remainder is less than the degree of the divisor.
So, we cannot continue the division any further. This chapter has a total of 7 exercises, and in these exercises, different methods of solving the pair of linear equations are described. Exercise 3. Exercises 3. Students must practise these exercises to master the method of solving linear equations. Algebraic conditions for number of solutions. Solution of a pair of linear equations in two variables algebraically — by substitution, by elimination.
Simple situational problems. In this chapter, students will get to know the standard form of writing a Quadratic Equation. The chapter goes on to explain the method of solving the quadratic equation through the factorization method and completing the square method. Solutions of quadratic equations only real roots by factorization and by using the quadratic formula. Relationship between discriminant and nature of roots. Situational problems based on quadratic equations related to day-to-day activities are to be incorporated.
Therefore, there are no real roots for the given quadratic equation in this case. This chapter introduces students to a new topic, Arithmetic Progression , i. The chapter constitutes a total of 4 exercises. In Exercise 5. Exercise 5. The next exercise, i. Motivation for studying Arithmetic Progression Derivation of the n th term and sum of the first n terms of A. Now, n th term for arithmetic progression is given as;. The chapter Triangles starts with the concept of a similar and congruent figure.
It further explains the condition for the similarity of two triangles and theorems related to the similarity of triangles. After that, the areas of similar triangles have been explained with a theorem. At the end of this chapter, the Pythagoras Theorem and the Converse of Pythagoras Theorem are described. Definitions, examples, and counter examples of similar triangles. Prove If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.
Motivate If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side. Motivate If in two triangles, the corresponding angles are equal, their corresponding sides are proportional, and the triangles are similar. Motivate If the corresponding sides of two triangles are proportional, their corresponding angles are equal, and the two triangles are similar. Motivate If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.
Theorem 6. In this chapter, students will learn how to find the distance between two points whose coordinates are given, and to find the area of the triangle formed by three given points. Along with this, students will also study how to find the coordinates of the point which divides a line segment joining two given points in a given ratio. Review: Concepts of coordinate geometry, graphs of linear equations.
Distance formula. Section formula internal division. This chapter will introduce students to Trigonometry. They will study some ratios of a right triangle with respect to its acute angles, called trigonometric ratios of the angles. The chapter also defines the trigonometric ratios for angles of 0 0 and 90 0. Further, students will also know how to calculate trigonometric ratios for some specific angles and establish some identities involving these ratios, called trigonometric identities.
Trigonometric ratios of an acute angle of a right-angled triangle. Proof of their existence well defined ; motivate the ratios, whichever are defined at 0 o and 90 o. Values of the trigonometric ratios of 30 0 , 45 0 and 60 0. Relationships between the ratios. Only simple identities to be given. Trigonometry Maths formulas for Class 10 cover three major functions Sine, Cosine and Tangent for a right-angle triangle. This chapter is the continuation of the previous chapter; here, the students will study the applications of trigonometry.
It is used in geography, navigation, construction of maps, and determining the position of an island in relation to the longitudes and latitudes. In this chapter, students will see how trigonometry is used for finding the heights and distances of various objects without actually measuring them.
They will get introduced to the term line of sight, angle of elevation, and angle of depression. Simple problems on heights and distances. Problems should not involve more than two right triangles.
The line of sight is the line drawn from the eye of an observer to the point in the object viewed by the observer. The angle of elevation of the point viewed is the angle formed by the line of sight with the horizontal when the point being viewed is above the horizontal level, i. The angle of depression of a point on the object being viewed is the angle formed by the line of sight with the horizontal when the point is below the horizontal level, i.
Assuming that the above three conditions are known, how can we determine the height of the minar? In earlier classes, students have studied about a circle and various terms related to a circle, such as a chord, segment, arc, etc. In this chapter, students will study the different situations that arise when a circle and a line are given in a plane.
Tangent to a circle at point of contact 1. Prove The tangent at any point of a circle is perpendicular to the radius through the point of contact. Prove The lengths of tangents drawn from an external point to a circle are equal.
Theorem Case 2: There is one and only one tangent to a circle passing through a point lying on the circle. This chapter consists of a total of 2 exercises. Whatever students have learned about construction in earlier classes will also help them. In Exercise Also, when it comes to exercises in a chapter, do not wait until the end of the chapter to prepare them. Learn all the topics and formulas, and apply them to their example questions by examining their formulas and methods.
Practice the questions in the exercise one by one, if you see that two or more of the questions are similar. But it is tough for you to answer the other parts, try to focus only on the parts that are unique or that are challenging for you.
Finally, circulate forward to the exercises of the chapter of maths class 10 notes. Practice every question of an exercise completely. You can do all the exercises in this manner. I recommend that you should practice each question yourself and if you find any difficulty simply check out our provided 10th class maths solution pdf Urdu and English medium. Even though the authors tried their best. Sometimes errors happen unavoidably. It would be appreciated, however, if any suggestions were made for further improvement.
