The area of the triangle whose vertices are \(i, \omega\) and \(\omega^2\) is (Where \(\omega\) is a complex cube root of unity other than \(1, \mathrm{i}\) is an imaginary number) ______ sq.units
- A \(\frac{3 \sqrt{3}}{4}\)
- B \(\frac{\sqrt{3}}{2}\)
- C \(\frac{3 \sqrt{3}}{2}\)
- D \(\frac{\sqrt{3}}{4}\)
Answer & Solution
Correct Answer
(D) \(\frac{\sqrt{3}}{4}\)
Step-by-step Solution
Detailed explanation
Vertices: \(z_1 = (0, 1)\), \(z_2 = (-\frac{1}{2}, \frac{\sqrt{3}}{2})\), \(z_3 = (-\frac{1}{2}, -\frac{\sqrt{3}}{2})\) Area \( = \frac{1}{2} |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|\)
