Question

if theta equals to 45 degree then value of 1-cos 2 theta / sin 2 theta is​

Answer 1

hope this answer helps you

Answer 2

Answer:

Given that, ∅ = 45°

We know that, cos(90°)=0 and sin(90°)=1

$→\frac{1 - \cos(2 \theta) }{ \sin(2 \theta) }\\ = \frac{1 - \cos(2 \times 45°) }{ \sin(2 \times 45°) } \\= \frac{1 - \cos(90°) }{ \sin(90°) } \\ = \frac{(1 - 0)}{1} = \frac{1}{1} = \boxed1✓$

• 1 is the right answer.
