# Complex Numbers

- Euler's Formula in Trigonometry - Euler's Formula in Trigonometry relates trigonometric functions with the complex exponential function through the formula e^(iθ) = cos(θ) + i*sin(θ), for an angle θ in radians.
- Trigonometric Form of a Complex Number - The trigonometric form of a complex number provides a way to express a complex number using modulus and argument.
