Which graph represents the polar curve r = 4cos(30)?
stepan [7]

The equation of the polar curve r = 4\cos(3\theta) is an even cosine function.

<h3>Polar curves</h3>

In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point

The equation of the polar curve is given as:

r = 4\cos(3\theta)

To graph the polar curve, we make use of the following representations:

  • r represents the y-axis
  • \theta represents the x-axis

Using the above representation, we can graph the polar curve

See attachment for the graph that represents r = 4\cos(3\theta)

timama [110]

Option 2 8-12i is correct.

Step-by-step explanation:

The conjugate of the complex number is obtained by changing the sign of the imaginary part.

In complex number 8+12i

8 is the real part and 12i is the imaginary part

The conjugate of 8+12i is 8-12i

So, Option 2 8-12i is correct.
