Question:
<p>From the point (4, 6) a pair of tangent lines are drawn to the parabola, y<sup>2</sup> = 8x. The area of the triangle formed by these pair of tangent lines and the chord of contact of the point (4, 6) is:</p>
<p style="display:inline">2</p>
<p style="display:inline">4</p>
<p style="display:inline">6</p>
<p style="display:inline">8</p>
Step-by-Step Solution
Key Concept: The area of the triangle formed by tangents from (x1, y1) and the chord of contact to the parabola y^2 = 4ax is given by the formula Area = (y1^2 - 4ax1)^(3/2) / (2a).
<p>2</p>
