respectively and we also say that +1 is the constant term in it. Q.14 Calculate 103 X 107 using algebraic identities. Make the most out of the Maths Formulas for Class 9 prepared by subject experts and take your preparation to the next level. (ii) Give an example of a monomial of degree 16. 2. Example : cumference of circle r - radius of circle Where 2 & are constants. Variables : A symbol which may be assigned different numerical values is known avariable. The position of the point P from origin on x-axis is called x-coordinate and the position of P from origin on y-axis is called y-coordinate. The List of Important Formulas for Class 9 Coordinate Geometry is provided on this page. Origin: The point where both the axis intersect each other is known as origin. Connected by some or all of the operations +, -, X and is known as algebraic expression. Geometry Shapes Formulas for Class 9 : Geometric Figure: Area: Perimeter Rectangle: A= l × w: P = 2 (l+w) Triangle: A = 1/2× bh: P = a + b + c: Trapezoid: A = 1/2×h(b1+b2) P = a + b + c + d: Parallelogram: A = bh: P = 2 (a+b) Circle: A= πr 2: C = 2πr Factor theorem : Let be a polynomial of degree and let a be any real number. Class 9 Heron’s Formula: Area of Triangle = $$\sqrt{s(s-a)(s-b)(s-c)}$$ Perimeter of Triangle =$$a+b+c$$ Semi perimeter of Triangle =$$\frac{a+b+c}{2}$$ Where, a, b, c are Side of Triangle; Class 9 Surface Areas and Volumes Formulas: Surface area of Cube = $$6a^{2}$$ Volume of a cube = $$a^{3}$$ Where, a is the side length of the cube. Q.13 Calculate (997)2 using algebraic identities. Q.24 Which of the following expression is a polynomial? Coefficients : In the polynomial coefficient of Example : 7, 3, -2, 3/7, etc. r - radius of circle Where 2 & are constants. 1. CBSE Syllabus Class 12 Maths Physics Chemistry ... CBSE Syllabus Class 11 Mathematics biology chemistry ... CBSE Syllabus Class 10 Maths Science Hindi English ... CBSE Syllabus Class 9 Mathematics Science English Hindi ... Revised Syllabus for Class 12 Mathematics. When XX’ and YY’ intersect each other then the plane is divided into four parts. Identity : Identity is a equation (trigonometric, algebraic ) which is true for every value of variable. Rene Descartes was a French mathematician. 6. Constants : A symbol having a fixed numerical value is called a constant. Revise the entire concepts in a smart way taking help of the Maths Formulas for Class 9 Coordinate Geometry. Methods of Factorization : Factorization by taking out the common factore.g. Q.8 Find the value of a for which is a factor of the polynomial. Remark : Finding the zeroes of polynomial p(x) means solving the equation p(x)=0. We have everything covered right from basic to advanced concepts in Coordinate Geometry. while C and r are variable Q.2 Write the degree of each of the following polynomial. Algebraic expressions : A combination of constants and variables. Q.5 Find the zeros of the polynomials given below : Q.6 Find the remainder when is divided by. Constant polynomial : A polynomial containing one term only, consisting a constanterm is called a constant polynomial the degree of non-zero constant polynomial is zero. If a and b are respectively abscissa and ordinate, then the coordinates are (a, b). 2. The lines XX’ and YY’ are called axes i.e., XX’ is the x-axis and YY’ is y-axis. Example : 7, 3, -2, 3/7, etc. The plane is known as Cartesian plane or XY plane. Degree of a polynomial in one variable : In case of a polynomial in one variable the highest power of the variable is called the degree of the polynomial. Classification of polynomials on the basis of degree. Maths Formulas for Class 9 Coordinate Geometry 1. Ordinate: The distance of a point P from x-axis is called its ordinate. Some algebraic identities useful in factorization: Q.1 Which of the following expressions is polynomial? Quadrant These parts are called quadrants. Factorization : To express a given polynomial as the product of polynomials each of degree less than that of the given polynomial such that no such a factor has a factor of lower degree, is called factorization.
