Euler's formula is .[2] It is remarkable in that it relates trigonometric function functions with complex numbers. Euler's formula maps the natural constant e raised to the complex exponent to the complex plane using the trigonometric expression . This equation is true only if the angle θ is measured in radians. Euler's formula is named after Leonhard Euler who published it in its present form in 1748. Leonard Euler was a very prolific mathematician. Note that the phrase Euler's Formula is used to indicate different formulas in different disciplines.
