The Euler's formula for any real number x is e^(ix) = cos(x) i sin(x), where e is the base of the natural logarithm (approximately 2.718), i is the imaginary unit (i = √(-1)), and cos and sin are the trigonometric functions. To visualize Euler's formula in the complex plane, consider the following: - The complex plane is a 2D plane where the x-axis represents the real part of a complex number, and the y-axis represents the imaginary part. - The expression e^(ix) represents a point on the unit ci

📌Euler's formula is a fundamental equation in complex analysis that shows a deep connection between exponential functions and trigonometric functions. It states that *e* raised to the power of *i* times *x* equals the cosine of *x* plus *i* times the sine of *x*. In simple terms, it expresses how complex exponentials can represent circular motion. This formula is widely used in engineering, physics, and mathematics because it elegantly links exponential growth, rotation, and wave behavior in a
