Question
Problem of weed is more in case
ofSolution
The problem of weed is more in case of upland direct seeded rice which is also known as aerobic rice since puddling is not done here as rice is directly sown in field and also no transplanting is done.
Find the maximum value of 18 sin A + 7 cos A.
- If sin 2a = (3/2), then find the value of (sin a + cos a).
- If X = 15°, find the value of:
sin²(3X) + cos²(4X) - tan²(2X) cot 13Ëš Â
 cot 14˚  ...If 2x = cosec @ and 4/x = cot @ then the value of 2(x ² - 1/x ² ) is
Solve for 0° ≤ θ ≤ 360°:
