Step-by-step explanation: aww I don't know what happened Google it.

Let

I

1

=

(

tan

x

+

cot

x

)

d

x

=

2

sin

x

+

cos

x

2

sin

x

cos

x

d

x

=

2

sin

x

+

cos

x

1

(

sin

x

cos

x

)

2

d

x

If

sin

x

cos

x

=

u

then

d

u

=

(

sin

x

+

cos

x

)

d

x

So

I

1

=

2

1

1

u

2

d

u

=

2

sin

1

u

=

2

sin

1

(

sin

x

cos

x

)

Similarly

I

2

=

(

tan

x

cot

x

)

d

x

=

2

sin

x

cos

x

2

sin

x

cos

x

d

x

=

2

cos

x

sin

x

(

sin

x

+

cos

x

)

2

1

d

x

If

sin

x

+

cos

x

=

v

then

d

v

=

(

cos

x

sin

x

)

d

x

So

I

2

=

2

1

v

2

1

d

v

=

2

ln

v

+

v

2

1

=

2

(

ln

(

sin

x

+

cos

x

)

+

2

sin

x

cos

x

)

I

=

1

2

(

I

1

+

I

2

)

=

1

)

2

ln

(

sin

x

cos

x

)

+

2

sin
