Why do we use complex exponential?

Complex exponentials provide a convenient way to combine sine and cosine terms with the same frequency.

What is the role of exponential function?

An exponential function is a mathematical function, which is used in many real-world situations. It is mainly used to find the exponential decay or exponential growth or to compute investments, model populations and so on.

What do you mean by complex exponential function?

The complex exponential. The exponential function is a basic building block for solutions of ODEs. Complex numbers expand the scope of the exponential function, and bring trigonometric functions under its sway.

How do you use complex exponential?

If you have a complex number z = r(cos(θ) + i sin(θ)) written in polar form, you can use Euler's formula to write it even more concisely in exponential form: z = re^(iθ).
