Exponential (Radians) to Rectangular Form (Level 1)

This topic focuses on practicing the conversion of complex numbers from exponential form (expressed in radians) to rectangular form. Each problem presents a complex number in exponential notation, for which students are tasked with finding the equivalent rectangular form. Multiple choice answers accompany each question, providing various options for the rectangular forms from which to choose. This involves understanding and applying the Euler’s formula, a crucial concept in complex numbers.
