Question

Find the value of sin(x/2),cos(x/2) and tan(x/2). if tanx= -4/3 in 2rd quadrant

Answer 1

Answer:

sin (-26.5651) = -0.4472

cos (-26.5651) = 0.8944

tan (-26.5651) = -0.5

Step-by-step explanation:

tan x = -4/3

x = atan(-4/3) = -53.13

x/2 = -53.13/2 = -26.5651

sin (-26.5651) = -0.4472

cos (-26.5651) = 0.8944

tan (-26.5651) = -0.5
