\(\rm \frac{k-k\cot^230^\circ}{1+\cot^2 30^{\circ}}\)= sin2 60° + 4 tan245° - cosec260°
वापरलेली संकल्पना:
गणना:
\(\rm \frac{k-k\cot^230^\circ}{1+\cot^2 30^{\circ}}\)= 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 चे मूल्य -6.83 आहे.
