WebThe proof by mathematical induction (simply known as induction) is a fundamental proof technique that is as important as the direct proof, proof by contraposition, and proof by contradiction. It is usually useful in proving that a statement is true for all the natural numbers \mathbb {N} N. 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.
