isÂSolution
According to FAO, area having LGP (length of growing period) between 1to 74 days classified as Arid area
If X = 15°, find the value of:
sin²(4X) + cos²(3X) - tan²(2X)What is the value of [(tan 5θ + tan 3θ)/4 cos 4θ (tan 5θ – tan 3θ)]?
The minimum value of 9 cos2 θ + 36 sec2 θ isÂ
If tanθ – cotθ = a and cosθ + sinθ = b, then (b2 –1)(a2 + 4) = ?
Find the value of the given expression.
3 × (sin 30° + cos 60°)
