Understanding Polar and Rectangular Forms

Polar form and rectangular form are two ways to represent complex numbers. Polar form is a way of expressing complex numbers using the magnitude (or length) and angle of the number, whereas rectangular form represents complex numbers using their real and imaginary parts.

Polar Form

In polar form, a complex number is represented as:

z = r(cos(θ) + isin(θ))

where:

• z is the complex number
• r is the magnitude (or length) of the number
• θ is the angle in standard position

Rectangular Form

In rectangular form, a complex number is represented as:

z = a + bi

where:

• z is the complex number
• a is the real part
• b is the imaginary part
• i is the imaginary unit (i = √(-1))

Converting Between Polar and Rectangular Forms

Converting between polar and rectangular forms involves using trigonometric functions. To convert from polar to rectangular form, you can use the following formulas:

a = rcos(θ) b = rsin(θ)

To convert from rectangular to polar form, you can use the following formulas:

r = √(a^2 + b^2) θ = arctan(b/a)
