Answer 1

Hello !

Correct question :-

$\dfrac{1-tan²(45)⁰}{1+tan²(45)⁰}$ = ?

Concept:-

• put the value of tan45⁰ = 1
• and then square it as it is given in Ques.

Solution:-

$\implies$ $\dfrac{1-tan²45}{1+tan²45⁰}$

$\implies$ $\dfrac{1-(1)²}{1+(1)²}$

$\implies$ $\dfrac{1-1}{1+1}$

$\implies$ $\dfrac{0}{2}$ = 0 .
