Question
Stenospermocarpy refers to
Solution
In this unique type of parthenocarpy, fertilisation takes place and the seed develops but finally aborts. This unique type of parthenocarpy can be seen in seedless grapes and watermelons.
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?
