CBSE Class 10 Maths Formulas Chapter-04 | Quadratic Equations

Quadratic equation Chapter 4 Class 10 Basic concepts on Quadratic Equation class 10, chapter 4,  Nature of roots, Discriminant, Quadratic Formula, method of completing the square. Complete explanation of quadratic equations QUADRATIC EQUATION :-  An equation whose degree is 2 is called a quadratic equation. General Quadratic Equation is  ax 2 + bx + c = 0  Here "a" is the coefficient of x 2  ,  "b" is the coefficient of x and  "c" is the constant term.  Difference between the quadratic equations and quadratic polynomials. Quadratic equations are very similar to the quadratic polynomials. But they are different from each other because of the following reasons. Quadratic Equations Quadratic Polynomials General Quadratic Equations is    ax 2  + bx + c = 0 General Quadratic Polynomial is  P(x) = ax 2  + bx + c Solutions of quadratic equations are called its roots. Sol

Limit and Continuity Class 11 | Ch-12

Limit and Continuity Class 11   Basic concepts and formulas based on limit and continuity important for the students of classes 11 and 12. Important formulas of chapter 13 class 11 and important formulas necessary for the students of class 12 chapter 5 Introduction Limit and continuity is the introduction of calculus. Calculus is that branch of Mathematics which mainly deals with the study of change in the value of a function as the point in the domain changes.   Definition:  Suppose f is a real function on a subset of the real numbers and let c be a point in the domain of f. Then f is continuous at c if  ALGEBRA OF LIMITS Let f(x) anf g(x) are two functions such that     and     exist. 1)     2)   3)    4)     Limit of constant function remain constant Undefined terms:     all these terms are called undefined terms If we put the limit and we got undefined form then at that point limit cannot be calculated. In this case we first simplify the functions by applying some form
