Question

Determine the eccentricity, the type of conic, and the directrix for r =2.1/1+0.7cod theta​

Answer 1

Answer:

The equation represents an ellipse with an eccentricity of 0.7.

Step-by-step explanation:

The given equation is

$r=\frac{2.1}{1+0.7cos\theta}$

This equations represents a conic section in polar form, where the coefficient of the cosine function is the eccentricity of the conic section.

So, in this case, the eccentricity is $e=0.7$, which indicates that the equation belong to an ellipse, because the eccentricy of ellipses are between 0 and 1.

Therefore, the equation represents an ellipse with an eccentricity of 0.7.
