find the number of angular bisectors that can be drawn to the given figure.

Find the number of angular bisectors that can be drawn to the given figure. => 13 or 11 or 9 or ∞..

Geometrical representation of a Complex number, Argand diagram - Since every complex number z = x + iy is an order pair of real numbers (x, y), it can therefore be represented by a point P(x,y) in the xy plane by taking the real part along the x-axis and the imaginary ..

Introduction - The word 'Induction' means method of reasoning from individual cases to general ones or from observed instances to unobserved ones. Many important mathematical formulae are such that a result is formed by some means which does not provide for a direct proof. Mathematical Induction is..

We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. The difference between these two values is called the absolute error. Absolute Error = Original h..

HCF of a polynomial is the largest monomial, which is a factor of each term of the polynomial. We can factorise a polynomial by finding the Highest Common Factor (HCF) of the terms of the expression and then dividing each term by its HCF. HCF and the quotient obtained are the factors of t..

To insert n Harmonic Means between two given quantities. Let a and b be two given quantities. It is required to insert n harmonic means h 1 , h 2 , h 3 ,....h n between the quantities a and b. Let d = common difference of the A.P. ..

Introduction - We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. Suppose a measurement is recorded as 0.6204 cm. It means that the measurement was made correct..

Significant Figures and Measuring Instruments - Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement..

If two sets are given, a set can be formed by using all the elements of the two sets. Such a collection is called the union of the given set..

The total number of all possible subsets of a given set containing n elements is 2 ..
