If the eccentricity of a parabola is e, what is the value of e?
Step 1: Understand what eccentricity means. Eccentricity is a number that describes how much a conic section (like a circle, ellipse, parabola, or hyperbola) deviates from being circular.
Step 2: Know the types of conic sections. There are four types: circle (e=0), ellipse (0 < e < 1), parabola (e=1), and hyperbola (e > 1).
Step 3: Identify the conic section in the question. The question is about a parabola.
Step 4: Recall the definition of eccentricity for a parabola. For a parabola, the eccentricity is always equal to 1.
Step 5: Conclude that since the question is about a parabola, the value of eccentricity (e) is 1.
Eccentricity of Conic Sections – Eccentricity is a measure of how much a conic section deviates from being circular. For parabolas, the eccentricity is defined as 1.
