## How do you convert to rectangular form?

To convert from polar coordinates to rectangular coordinates, use the formulas x=rcosθ and y=rsinθ.

**What are the roots of a complex number?**

The roots of a complex number are also given by a formula. A complex number a + bı is an nth root of a complex number z if z = (a + bı)n, where n is a positive integer.

**How do you convert from complex to rectangular polar?**

To convert from polar to rectangular, find the real component by multiplying the polar magnitude by the cosine of the angle, and the imaginary component by multiplying the polar magnitude by the sine of the angle.

### What is the value of i Square in complex number?

An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.

**Which is the square root of a complex number?**

Square root. Square root of complex number (a+bi) is z, if z 2 = (a+bi). Here ends simplicity. Because of the fundamental theorem of algebra, you will always have two different square roots for a given number.

**Are there two solutions to the Complex Number Calculator?**

There are 2 solutions, due to “The Fundamental Theorem of Algebra”. Your expression contains roots of complex numbers or powers to 1/n. This calculator does basic arithmetic on complex numbers and evaluates expressions in the set of complex numbers.

#### How to convert complex numbers into angle notation?

The calculator also converts a complex number into angle notation (phasor notation), exponential, or polar coordinates (magnitude and angle). Enter expression with complex numbers like 5* (1+i) (-2-5i)^2

**Is there a calculator that converts polar numbers to rectangular numbers?**

Below is an interactive calculator that allows you to easily convert complex numbers in polar form to rectangular form, and vice-versa. There’s also a graph which shows you the meaning of what you’ve found. For background information on what’s going on, and more explanation, see the previous pages,
