Question

1-tan² 45°/1+tan² 45°​

Answer 1

Answer:

0

Step-by-step explanation:

As tan^2 45 = 1

thus in numerator 1 - 1 will be zero thus the answer will be zero

Answer 2

Answer: 0

Step-by-step explanation:

Solving numerator First:

1-$tan^{2}$45°

value of tan45° = $\frac{sin45}{cos45}$ = $\frac{1}{\sqrt[]{2} }$ /$\frac{1}{\sqrt[]{2} }$ = 1

Therefore tan²45 = 1² = 1

Hence, 1-tan²45° = 1-1 = 0

Therefore Numerator = 0

Hence Answer = 0
