Given :

sinø + cosø = √3

To prove :

tanø + cotø = 1

Proof :

We have ;

sinø + cosø = √3

Now ,

Squaring both the sides , we have ;

=> (sinø + cosø)² = (√3)²

=> sin²ø + cos²ø + 2sinø·cosø = 3

=> 1 + 2sinø·cosø = 3 { sin²ø + cos²ø = 1 }

=> 2sinø·cosø = 3 - 1

=> 2sinø·cosø = 2

=> sinø·cosø = 2/2

=> sinø·cosø = 1

Now ,

=> tanø + cotø = sinø/cosø + cosø/sinø

=> tanø + cotø = (sin²ø + cos²ø)/cosø·sinø

=> tanø + cotø = 1/sinø·cosø

=> tanø + cotø = 1/1 { °° sinø·cosø = 1 }

=> tanø + cotø = 1

Hence proved.
