Options
- A1
- B0
- C-1
- Ddoes not exist
Correct answer
B. 0
Step-by-step solution
_ x 0 x^7 [ 1 x^3 ] RHL Let x=0+h , where h 0 _ h 0 h^7 [ 1 (0+h)^3 ]=0 aligned & LHL Let x=0-h where h 0 & _ h 0 (-h)^7 [ 1 (0-h)^3 ] & _ h 0 -h^7 (-1)=0 aligned aligned & LHL = RHL =0 & _ x 0 x^7 [ 1 x^3 ]=0 aligned
