Euler's Formula/Also known as

Euler's Formula: Also known as

Euler's formula in this and its corollary form, along with Euler's sine identity and Euler's cosine identity are also found referred to as Euler's identities.

However, this allows for confusion with Euler's identity:

$e^{i \pi} + 1 = 0$

To compound the confusion, Euler's formula is also itself often referred to as Euler's identity.

It is wise when referring to it by name, therefore, to ensure that the equation itself is also specified.
