Imaginary No
A number is an imaginary number when it multiplied by square root of negative no. An imaginary number is the square root of a negative number and does not have a tangible value.”Complex” numbers have two parts, a “real” part (being any “real” number that you’re used to dealing with) and an “imaginary” part (being any number with an […]
3D shapes
3D Shapes Resources. 3D shapes are solid objects that have three dimensions. These dimensions are length, width, and height. While 2D shapes are flat, 3D shapes objects that have depth to them. 3D Shapes
Circle theorem
Circles Geometry The measure of an arc of a circle is equal to the measure of the central angle that intercepts the arc. 1. Inscribed angle theorem. The measure of an inscribed angle is equal to one-half the measure of its intercepted arc. Circle Geometry
Lines , angles and triangle
Pairs of angles formed when a third line (a transversal) crosses two other lines. These angles are opposite sides of the transversal and are in between the other two lines. Line, angle and triangle
Factorisation
Factorisations processes we applied bracket to take common term out. Also we apply difference of square of variable. Hence we reduce no of terms in expression. Therefore factorisation and expansion are reverse process. Factorization
Properties of indices
Laws of Exponents. Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. Law of Indices. To manipulate expressions, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 3 4 and 3 2 can be manipulated […]
Quadratics
First of all this post consists of questions of factorisation of quadratics . 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 […]
Completing Square form
Completing form is to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial. Completing the square is a technique for converting a quadratic polynomial of the form ax2 + bx + c to a(x-b)2+c. Hence this method is used to convert. Similarly it use to […]
Function
A functions 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
