Question
A cropping system where land is handed over to the
succeeding crop before the harvest of standing cropSolution
Relay cropping is type of cropping where land is handed over to succeeding crop before harvest of standing crop.
The minimum value of 9 cos2 θ + 36 sec2 θ isÂ
If x = r sin A cos B, y = r sin A sin B and z = r cos A, then find x² + y² + z².
IfÂ
If sinθ = 5/13 for an acute angle θ, find:
(a) cosθ, (b) tan(90° − θ).
If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
Find the maximum value of 18 sin A + 7 cos A.

If cot A = √3, then what will be the value of sin4 A?
