Question

find the values of cosec ( - 11110° ).

Answer 1

hello rihan^^


here is u r answer ^^

thank for asking this question ^^


_________________________________

180 ° = π©

= > ( -1110 ° ) = [ π / 180 × 1110 ]©

= > 【 37π / 6 】©

so ,

cosec (-1110°) = - cosec ( 1110°)

[ cosec ( - theta ) = - cosec theta.]


= > - cosec ( 37π / 6)

=> - cosec ( 6π + π / 6)

= > - cosec π /6 [ cosec(2nπ + theta) = cosec theta]

= > -2.


=====================================

I hope help u.
