The speaker introduces the integral of secant x, initially rewriting it as 1 over cos x []. The core strategy is to multiply and divide by cos x to introduce sine x and cos x terms, enabling a substitution where sine x becomes 't' and cos x becomes 'dt' []. This manipulation transforms the integrand into a form that can be simplified using the identity cos²x = 1 - sin²x [].
