Even and odd functions

Image
 Even & Odd function  Every function has its own identity . Let,  a function f(x) is defined in a particular interval . If it satisfies the condition that, f(x)=f(-x) Then the function f is even function .  Whereas , if  f(-x)= -f(x)  Then the function is odd function.  The story is not over yet. There is a property which differentiate the odd function from even function. If I draw the graph of f(x) function which is odd then I will find no symmetry about y axis but if I take and even function and draw its graph then it will be symmetric about y axis. Here are two examples of even and odd function with their graphs.. Here we have to note that some functions are neither even not odd these are called NENO functions.

Let's feel math .

Let's feel mathematics. A controversy :  teachers of every subject used to proof that their subject is the best and is the soul of universe. In every country you will find teachers who are busy to such . But I will not try to prove in front of you that mathematics is the best subject. I will just try to make you feel the mathematics from your heart and soul. Love for mathematics. : Love for mathematics is extremely important during the study of mathematics in any university or college or even High school . How do you know that you have loved Mathematics? Suppose you are attempting an online math examination which can be anytime paused. Suppose your mother is asking you for taking food pausing the examination thereafter. But if you say to her that, " Mom I will eat after the completion of the exam" , it is your love for mathematics.
