Quadratics
First of all this post consists of questions of factorisation of quadratic equation. The method use to find solutions are splitting middle term and another method is formula . We also find the nature of roots of equation. The method is use to find nature is discriminant (D= b2-4ac). Discriminant is also used in formula […]
Binomial Theorem
This post is about binomial expansion of two terms expression. Also in this post question, like first of all find particular term and also find coefficient of particular terms. Moreover topic is in AS-level , A-level , IBDP Math HL and SL. To find the coefficient of term we use pascal triangle Binomial Theorem
Inverse and Composite function
Inverses and Composites are two important concept of functions. Composite function is defined as one function defined inside another function. Like ff(x)) or f(g(x)) etc. Concept of inverse is interchange of variables . Inverse notations are f-1(x),g-1(x) etc. Hence interchange is inverse. Therefore function and its inverse is reflection about y = x. Inverse and composite

Inverse of function
Inverse of functions is an important concept . Domain values and Range values gets interchange . Due to these values of functions, continuity of function also change. Graph of inverse function also change and become y-axis oriented. Therefore graph of inverse is reflection of function graph about y = x. Inverse of Function
Function
A function f(x) tells you what to do with the input, but, to be completely defined, function also need to know what type of input is permitted to go into the function. Function
Rational and Reciprocal functions
A rational functions is a function of the form f(x)=p(x)/q(x), where p(x) and q(x) are polynomials and q(x)≠0 ,q(x)≠0 . The domain of a rational function consists of all the real numbers x=0 except those for which the denominator is x= 0 . reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1.. The […]
Conics
Conics section is a curve section of cone. Conic section is obtained as the intersection of the surface of a cone with a plane. Because of this is called cone. Conic graphs can be “slanty”, Therefore conics equation is seems like circle. Because a conics generated by the intersection of a plane and a circular cone […]
Parametric Equation
Parametric Equation. Namely, x = f ( t ), y = g ( t ) t D. where D is a set of real numbers. The variable t is called a parameter and the relations between x, y and t are called parametric equations. The set D is called the domain of f and g and it […]
