## Welcome to 11th grade math!

Sets : The concept of set is basic in all branches of mathematics. It has proved to be of particular importance in the formations of relations and functions.
Relations and Functions : In mathematics, we come to across relations such as i) line l is parallel to line m ii) number m is less than number n . In all these we notice that a relation involves pairs of objects in certain order. This section is devoted to the study of relations and functions in mathematics.
Mathematical induction : The process of reasoning from general to particular and the other is known as the process of induction. In algebra or in other disciplines of mathematics, there are certain results or statements that are formulated in terms of n , where n is a positive integer. To prove such statements we use a specific technique, is known as the “Principle of Mathematical Induction".
Logarithms : It is a specific process that reduces the amount of work involved in multiplying and dividing large numbers.
Complex Numbers : Complex number is a number of the form a + ib, where a and b are real numbers and i is the imaginary unit which has the property of i 2 = -1
Linear Inequations : 13x <250 such equations are called linear inequations.The study of inequations is very useful in solving problems in the fields of science, mathematics, statistics, optimization problems, economics,psychology etc.
Quadratic Equations : In this section ask-math provides you the quadratic equations with real coefficients but having negative discriminant.
Sequences and series : In this section ask-math covers all types of sequences such as arithmetic progression (A.P), Geometric progression (G.P) and harmonic progression.
Trigonometric functions : In this section, ask-math provides the circular function and their properties. Such as conversion of angles from radian to degree, signs of trigonometric functions, domain and range of trigonometric functions, sum and difference of angles etc.
Cartesian system of rectangular co-ordinates : This section provides you the distance formula, section formula , area of triangle using coordinates , parametric equation of line etc.
Straight line and family of straight line: In this section, we shall derive the various forms of the equation of a line including the lines parallel to axes and the oblique ones.
