WebWhat is induction in calculus? In calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms.

Chapter IV Proof by Induction - Brigham Young University

One definition of induction is to “find general principles from specific examples”. When we use proof by induction, we are looking at one specific example (the base step) and a general case (the induction step). Together, these prove the statement that we are investigating for all natural numbers. See more Proof by induction works because we are showing that a statement is true for the first case, and also that if it is true for one case, it is true for the next. A good analogy is dominoes. If you set up dominoes close together, you can … See more You should use proof by induction when you want to prove a statement for all natural numbers N. For example, you can use mathematical induction to prove that the sum of the first N integers is N(N + 1) / 2, or: 1. 1 + 2 + … + … See more To do a proof by induction, start with the base case. This case is usually easy. It also reassures you that the statement is true for at least one case (which is helpful if you statement is still only conjecture!) Next, go to the … See more WebLet P be a polynomial with integer coefficients and degree at least two. We prove an upper bound on the number of integer solutions n ≤ N to n! = P (x) which yields a power saving over the trivial bound. In particular, this applies to a century-old problem of Brocard and Ramanujan. The previous best result was that the number of solutions is o (N).The proof …
