was in the news in March 2024?Solution
The Sela Tunnel connects Assam and Arunachal Pradesh. Inaugurated virtually by Prime Minister Narendra Modi, this project enhances strategic connectivity and fosters socio-economic development in the region. Located at an altitude of 13,000 feet, it ensures all-weather access to Tawang via Sela Pass, bolstering defense logistics as well.

Take θ = 450
If A and B are complementary angles, then the value of-
sin A cos B + cos A sin B – tan A tan B + sec 2
- Simplify the following trigonometric expression:
15 cos 27° sec 63° − 9 cot 61° tan 29° tan 1˚ × tan 2˚× …………………….tan 88˚ × tan 89˚ = ?
if a sin 45 ˚ = b cosec 60 ˚ then find the value of a⁴/b⁴
...What is the value of cosec30° sec30°?
- If X = 15°, find the value of:
sin²(4X) + cos²(3X) - tan²(2X) - If sin(A + B) = √3/2 and cos(A + 2B) = 0, where 0° < A, B < 90°, then find the value of tan(2A).
