Proofs by strong induction

WebJul 6, 2024 · In a "strong" induction proof, you are looking for a connection between P (any value of "n" between the base case and "k") and P (k + 1). If "strong" induction holds, so does regular induction, and vice-versa. Remember these two types of proofs are equivalent, and one is not inherently better than the other.

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.
