- 1f, x = (2n + 1)π2, n ∈ Z पर सतत नहीं है।
- 2f सर्वत्र सतत है लेकिन x = (2n + 1)π2, n ∈ Z पर अवकलनीय नहीं है।✓
- 3f सर्वत्र सतत है लेकिन x = nπ, n ∈ Z पर अवकलनीय नहीं है।
- 4f सर्वत्र अवकलनीय (everywhere differentiable) है।
सही उत्तर देखें
f सर्वत्र सतत है लेकिन x = (2n + 1)π2, n ∈ Z पर अवकलनीय नहीं है।
