r = 3 + 3cos(θ) polar equation would best match the desired audible range of the microphone.
<h3>How do you know if an equation is polar?</h3>
Determine the kind of polar equation.
The polar equation has the shape of a limaçon, and is written as r = a - b cos.
We just need to assess the equation throughout the range [0, 1] and then reflect the graph about the polar axis because the equation passes the condition for symmetry to the polar axis.
<h3>What is a polar in math?</h3>
The polar coordinate system in mathematics is a two-dimensional coordinate system in which the distance from a reference point and the angle from a reference direction are used to identify each point's location on a plane.
<h3>What is the meaning of polar form?</h3>
In addition to the rectangular form, a complex number can also be represented in polar form.
Typically, we write complex numbers as z = x + iy, where I is an imaginary integer.
However, in polar form, complex numbers are modeled as a union of argument and modulus.
Their common desire to destroy the ambitions of Prussia and Great Britain and to secure a definitive peace between their respective countries led them to seal their alliance with a marriage
