Welcome to the exhilarating world of inverse tangents! We promise to keep this journey interesting and even slightly humorous. So, buckle up and let’s dive into the magic of mathematics.
The inverse tangent, or arctan, is the inverse function of the tangent. Sounds daunting, right? But in simpler terms, it’s the angle whose tangent is a given number.
arctan(x) = tan^(-1)(x)
