The expression tan \(\frac{\tan A}{1-\cot A}+\frac{\cot A}{1-\tan A}\) can be written as:
sec A + cosec A
tan A + cot A
1 + sec A cosec A
1 + sin A cos A
On simplification, \(\frac{2^{10}-3^{10}}{5^{10}-6^{10}}\) is:
Cannot be defined
a negative rational number
neither a positive nor a negative rational number
a positive rational number
