- 1x के प्रत्येक बिंदु पर अवकलनीय है, लेकिन x = (2n + 1)π/2, n ∈ Z पर सतत नहीं है
- 2x = (2n + 1)π/2, n ∈ Z पर न तो सतत है और न ही अवकलनीय है
- 3x के प्रत्येक बिंदु पर सतत है, लेकिन x = (2n + 1)π/2, n ∈ Z पर अवकलनीय नहीं है✓
- 4x के प्रत्येक बिंदु पर सतत (continuous) और अवकलनीय (differentiable)
सही उत्तर देखें
x के प्रत्येक बिंदु पर सतत है, लेकिन x = (2n + 1)π/2, n ∈ Z पर अवकलनीय नहीं है
