Question

if π/2 <x<π ,then write the value of √(1-cos2x)/(1+cos2x)​

Answer 1

Step-by-step explanation:

y=

1−cos(2x)

1+cos(2x)

or.y=

(sin

2

(x)+cos

2

(x))−(cos

2

(x)−sin

2

(x))

(sin

2

(x)+cos

2

(x))+(cos

2

(x)−sin

2

(x))

or.y=

2sin

2

(x)

2cos

2

(x)

=

sin(x)

cos(x)

=cot(x)
