This math topic focuses on converting complex numbers from polar form to exponential form using radians. It includes multiple problems where students must calculate the exponential form of given complex numbers, represented in the format involving both cosine and sine functions of angles in radians. Each problem provides a trigonometric expression of a complex number and various options for its exponential counterpart, aiding in the understanding of the relationship between polar and exponential representations of complex numbers in the context of Euler's formula.
