    Are you allowed to use your calculator? If so, plug this into your calculator as : -(1/\cos((7\pi)/10)). Make sure you're in radian mode. You will get approximately 1.7013.

    First tell me

    Hi!Dave19
    ok first tell me if you know how to calculate the value of sin(18) where 18 is in degree.(I am asking this so that my answer may not become a new question for you).I think you want to calculate the value manually.please let me know about this also.

    (Pi)rad=180 degree
    so n rad=(180/pi) n degree
    You did not tell if you could find the value of sin18 manually.
