module to work with complex numbers

# Install 

```bash
npm install imagine-node
```

# Usage

```js
const complex = new Complex(1, 1);
complex.toString() // 1+i
const chainingComplex = complex
    .add({ real: 2, imaginary:3 })
    .sub({ real: 1, imaginary:1 })
    .multiply({ real: 2, imaginary:-3 })
    .div({ real: 2, imaginary:3 });
assert(chainingComplex.real === 2);
assert(chainingComplex.imaginary === -3);ç

complex
    .ln()
    .multiply({ real:1, imaginary:1 })
    .exp()
// Definitions and usage examples
cos() {
    return this
        .multiply({ imaginary:1 })
        .exp()
        .add(
            this.multiply({ imaginary:-1 }).exp()
        )
        .div({ real:2 });
}

acos() {
    return this
        .add(this.pow(2).sub(1).sqrt()[0])
        .ln()
        .multiply(Complex.im(-1));
}

asin() {
    return this
        .multiply(Complex.im())
        .add(Complex.re(1).sub(this.pow(2)).sqrt()[0])
        .ln()
        .multiply(Complex.im(-1));
}

atang() {
    return Complex.re(1)
        .sub(this.multiply(Complex.im()))
        .ln()
        .sub(Complex
            .re(1)
            .add(this.multiply(Complex.im()))
            .ln()
        )
        .multiply(Complex.im(0.5));
}

sin() {
    return this
        .multiply({ imaginary:1 })
        .exp()
        .sub(
            this.multiply({ imaginary:-1 }).exp()
        )
        .div({ imaginary: 2 });
