This Forgotten Rule About Integrating 1/X Will Shock Your Math Mind Mathematics is full of unexpected shortcuts and counterintuitive rules—some familiar, others totally mind-blowing. Among the lesser-known but profoundly helpful rules is the concept of integrating 1 over X, denoted mathematically as: \\[
\\int \frac{1}{X} \\, dX = \\ln|X| + C
\\] Yet all too often, students (and even seasoned learners) overlook a crucial detail that radically simplifies calculations—and that’s how absolute value and domain restrictions quietly shape outcomes. That hidden twist? The “forgotten” rule involves strict recognition of when X is positive or negative.
