Question

If tanx =3/4, π < x <3 π /2, find the values of sin (x/2), cos (x/2) and tan (x/2)?​

Answer 1

Answer:

0.94 , -0.31 and 3.00

Step-by-step explanation:

1. Tan x = 3/4
2. x = tan^-1(3/4)
3. x = 36.86 degrees
4. as x lies between 180 and 270 so add 180 to x therefore we get value of x = 216.86 degrees
5. x/2 = 216.86/2 = 108.43 degrees
6. Sin(x/2) = 0.94
7. Cos(x/2) = -0.31
8. Tan(x/2) = 3.00
