A QUASI-QUALITATIVE APPROACH TO LIMITS

The classical definition of limit of a function involving ‘epsilon and delta ’ is not readily understood by students studying calculus for first time. Though teaching/learning calculus from Non-standard models of number system and infinitesimals is relatively easier, it is not widely practised. Under these circumstances increased use of Landau symbols is suggested. This will promote a greater qualitative understanding of limits and the rate of growth of functions
