Find the exact values below. If applicable, click on \"Undefined\". tan(-2 pi/3) = csc (- 2 pi/3) =

Solution

Soultion1.

tan( -2/3)

= Sin(-2/3) / Cos(-2/3) ( Sin(-x) = -Sin(x) and cos(-x) = Cos(x))

  

= -1/0 ( Sin(-2/3) =-1 and Cos(-2/3) = 0

= Infinite =

tan (-2/3) =

answer

Solution =

csc( -2/3) = 1 / sin(-2/3) ( csc(x) = 1/sin(x))

= 1/(-1) (sin(-2/3) =-1)

= -1

Answer

csc(-2/3) = -1
