Introduction to Complex Equations

Complex equations are a fundamental concept in mathematics, particularly in the field of algebra and calculus. These equations involve variables that can be expressed in the form of a+bi, where a and b are real numbers and i is the imaginary unit, which satisfies the equation i^2 = -1. In this article, we will focus on solving the complex equation \dfrac{1}{z^{{\scriptsize -\dfrac{1}2}}}.

Understanding the Equation

The given equation is \dfrac{1}{z^{{\scriptsize -\dfrac{1}2}}}. To simplify this equation, we can start by rewriting it as z^{\dfrac{1}{2}}. This is because when we have a negative exponent, we can rewrite it as a positive exponent by taking the reciprocal of the base.

Simplifying the Equation

To simplify the equation z^{\dfrac{1}{2}}, we can express z in the form of a+bi. Substituting this into the equation, we get (a+bi)^{\dfrac{1}{2}}. To simplify this expression, we can use the binomial theorem, which states that (a+b)^n = \sum_{k=0}^{n} \binom{n}{k} a^{n-k} b^k.

Applying the Binomial Theorem

Using the binomial theorem, we can expand (a+bi)^{\dfrac{1}{2}} as \sqrt{a} + \dfrac{1}{2} \sqrt{a} \dfrac{1}{\sqrt{a}} bi. Simplifying this expression, we get \sqrt{a} + \dfrac{1}{2} bi.

Expressing the Solution in Polar Form

To express the solution in polar form, we can use the fact that z = re^{i\theta}, where r is the magnitude of z and \theta is the argument of z. Substituting this into the equation, we get \sqrt{r} e^{i\frac{\theta}{2}}.

Conclusion

In conclusion, we have solved the complex equation \dfrac{1}{z^{{\scriptsize -\dfrac{1}2}}} by rewriting it as z^{\dfrac{1}{2}} and expressing z in the form of a+bi. We then used the binomial theorem to simplify the expression and finally expressed the solution in polar form.
