注釈

Tan複素数のメソッドに対応して、Math.Tan実数のメソッド。The Tan method for complex numbers corresponds to the Math.Tan method for real numbers.

Tanメソッドでは、次の数式を使用して、複素数のタンジェントを計算`value`:The Tan method uses the following formula to calculate the tangent of the complex number `value`:

Sin(`value`) / Cos(`value`)Sin(`value`) / Cos(`value`)
