Ascending order and Descending order are basic but essential concepts in mathematics, introduced from Class 1 onwards.
Ascending: Smallest → Largest (going up).
Descending: Largest → Smallest (going down).
Memory Trick: 'A' in Ascending = 'A' in 'Add' — numbers get bigger as they go up.
Ascending Order means arranging numbers (or items) from the smallest to the largest.
Example: Arrange 45, 12, 78, 3, 56 in ascending order. → 3 < 12 < 45 < 56 < 78
Descending Order means arranging from the largest to the smallest.
Example: 78 > 56 > 45 > 12 > 3
| Type | Example |
|---|---|
| Ascending (A→Z) | Apple, Banana, Cherry, Mango |
| Ascending (numbers) | 2, 5, 9, 13, 21 |
| Descending (numbers) | 21, 13, 9, 5, 2 |
Ascending order means arranging numbers or items from the smallest to the largest (lowest to highest). For example: 3, 7, 12, 25, 40 is in ascending order.
What is the Value of sin 120°?
sin 120° = √3/2 ≈ 0.866. 120° is in 2nd quadrant: sin(120°)=sin(180°−60°)=sin 60°=√3/2. cos 120°=−1/2, tan 120°=−√3.
What is the Value of sin 37°?
sin 37° = 3/5 = 0.6 (standard approximation). Exact value: sin 37° ≈ 0.6018. From the 3-4-5 right triangle. Used in physics problems.
