A) \[1\]
B) \[0\]
C) \[-1\]
D) none of these
Correct Answer: B
Solution :
Given, \[f(0)=0,\,\,f'(x)={{\tan }^{4}}x\] \[\therefore \] \[\underset{x\to 0}{\mathop{\lim }}\,\frac{f(x)}{x}=\underset{x\to 0}{\mathop{\lim }}\,\frac{f'(x)}{1}\] \[=\underset{x\to 0}{\mathop{\lim }}\,\frac{{{\tan }^{4}}x}{1}=0\]You need to login to perform this action.
