## FAQs on Principle Of Mathematical Induction Video Lecture - Mathematics (Maths) Class 11 - Commerce

 1. What is the principle of mathematical induction?
Ans. The principle of mathematical induction is a method used to prove statements about natural numbers. It consists of two steps: the base case and the induction step. In the base case, the statement is proven true for the initial value (usually 0 or 1). In the induction step, the statement is assumed to be true for an arbitrary value, and then it is proven true for the next value. By repeating the induction step, the statement is proven true for all natural numbers.
 2. How is the principle of mathematical induction used in proofs?
Ans. The principle of mathematical induction is used to prove mathematical statements that involve natural numbers. To use induction in a proof, we first establish the base case by proving the statement true for the initial value. Then, we assume the statement is true for an arbitrary value and use this assumption to prove the statement true for the next value. By repeating this process, we can prove the statement true for all natural numbers.
 3. Can the principle of mathematical induction be used to prove statements about real numbers?
Ans. No, the principle of mathematical induction can only be used to prove statements about natural numbers. This is because the principle relies on the fact that there is a clear successor for every natural number (e.g., 0 has a successor of 1, 1 has a successor of 2, and so on). In contrast, real numbers do not have a clear successor, so the principle of mathematical induction cannot be applied to them.
 4. Are there any limitations to the principle of mathematical induction?
Ans. Yes, there are limitations to the principle of mathematical induction. One limitation is that it can only be used to prove statements about natural numbers. Additionally, the principle cannot be used to prove statements that are not true for all natural numbers. For example, if a statement is only true for even numbers, the principle of mathematical induction cannot be used to prove it. In such cases, alternative proof methods must be employed.
 5. What is the difference between weak and strong mathematical induction?
Ans. The difference between weak and strong mathematical induction lies in the assumptions made in the induction step. In weak induction, we assume the statement is true for an arbitrary value and use this assumption to prove the statement true for the next value. In strong induction, we assume the statement is true for all previous values up to the arbitrary value and use this assumption to prove the statement true for the next value. Strong induction allows for a stronger assumption, which can be useful in certain cases where weak induction may not be sufficient.
