LIMITS
The concept of limit of a function is a fundamental concept in calculus . Lmit of a Function : Suppose x is a variable and 'a' is a constant . If x takes value closer and closer to 'a' but not equal to 'a' , then we say that x tends to 'a' . Symbolically it is denoted by x⟶ a . we can observ that the value of x are very closed to a but not equal to a .When x > a and x takes values near a , foe example , x = a + 1/8 , x = a +1/4 ... etc, we say that x⟶a + (x tends to a from larger value ). When x < a and x takes value near a , for example , x = a - 1/2 , a = a - 1/4 , x = a - 1/8 ..etc., then we sat that x⟶ a - ( x tends to a from smaller value ). Definition of Limits : Let f(x) is very near to l . This is expressed by | f(x) - l | < ε for any ...
