A plane figure bounded by straight lines is called a rectilinear figure. A closed figure made up of 3 or more sides is called a polygon. If the measure of each interior angle of a polygon is less than 1800, then it is called a convex polygon. If the measure of at least one interior […]
The logarithm of any number to a given base is equal to the index to which the base should be raised to get the given number. The logarithm of a product is equal to the sum of the logarithms of its factors. The logarithm of a fraction is equal to the difference between the logarithm
When a polynomial is a product of two or more polynomials, each of the later polynomials is called its factors. The method of expressing a given polynomial as a product of two or more polynomials is called factorization. If a given polynomial contains a common factor which may be either a constant or a variable,

The angle which a straight line makes with the positive direction of the x-axis measured in the anticlockwise direction is called the inclination (or angle of inclination) of the line. The inclination is usually denoted by θ. If θ is the inclination of a line l, then tan θ is called the slope or gradient
If p(x) is a quadratic polynomial, then p(x) = 0 is called a quadratic equation. The general form of a quadratic equation, in the variable x, is ax2 + bx + c = 0, where a, b, c are real numbers and a not equal to 0. The value of x that satisfies an equation
A sequence is an arrangement of numbers in a definite order according to some rule. The various numbers occurring in a sequence are called its terms. We denote the terms of a sequence by a1, a2, a3…etc. Here, the subscripts denote the positions of the terms. In general, the number at the nth place is
A histogram is a graphical representation of a frequency distribution (in continuous form) in the form of rectangles with class intervals as bases and corresponding frequencies as heights, with no gap between any two successive rectangles. Frequency polygons are another way of displaying data using straight-line segments. The cumulative frequency is the accumulated or sum
