\(\rm \frac{k-k\cot^230^\circ}{1+\cot^2 30^{\circ}}\)= sin2 60° + 4 tan245° - cosec260°
ఉపయోగించిన భావన:
గణన:
\(\rm \frac{k-k\cot^230^\circ}{1+\cot^2 30^{\circ}}\)= sin2 60° + 4 tan245° - cosec260°
⇒ \(k \frac {1 - 3}{1 + 3}\) = 3/4 + 4 × 1 - 4/3
⇒ \(\frac {-k}{2}\) = 41/12
⇒ k = -41/6
⇒ k ≈ -6.83
∴ k విలువ -6.83.
