No one can help you EFFECTIVELY if you do not reveal what you know and what you don't know. Your questions reveal little to none on this. Tell us what you tried to understand, and at what point you don't. That way, the explanation we give will START from where you understand and builds on top of that. This is the most effective means to understand anything.kiru said:I thank you sir for giving me your suggestions.But as you said I don't make fun in seeing others responding me.Now only I got the oppurtunity to make use of this forum.As I have lots of doubts which my professors dont want to answer.I know that I am very low in knowledge.Yet in any way I want to acquire it.And from now onwards I will try to refine my approach of learning one at a time.Once again I sincerely thank you.You made me burst into tears.
