Answer 2

Answer:

0

Step-by-step explanation:

$\dfrac{1 - \cot^{2}45 }{1 + \cot^{2} 45}$

We know that ;

• cot 45° = 1

Substituting the value of cot 45° in the above equation ;

$\sf \frac{1 - (1) {}^{2} }{1 + (1) {}^{2} } \\ \\ \implies \sf \frac{1 - 1}{1 + 1} \\ \\ \implies \sf \frac{0}{2} \\ \\ \implies \sf 0$

Hence, the answer is 0.
