India signs its first concessional agreement with ____

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 (cos20°+sin 20°) /(cos20°-sin20°)

Simplify: sin (A + B) sin (A - B)

What is the value of cosec30° sec30°?

The minimum value of 77 sin θ + 36cosθ is

If tan A = 4/3, 0 ≤ A ≤ 90°, then find the value of sec A.

Simplifies-

(1 + tan²A) + (1+ 1 /tan²A)

[A] 1/ (sin²A-sin⁴ A)

[C] 1/ (cos² A-sin⁴ A)

If Sinθ + Cosθ =√2 Cos(90 -θ ), then find the value of Cotθ ?

tan 20˚ x tan 23˚ x tan 67˚ x tan 70˚ = ?
