Prove algebraically that r = 10/2+2sinTheta is a parabola

Step-by-step explanation:

We want to prove algebraically that:

is a parabola.

We use the relations

and

Before we substitute, let us rewrite the equation to get:

Or

Expand :

We now substitute to get:

This means that:

Square:

Expand:

This is a parabola (0,2.5) and turns upside down.

the answer is d
