**Question:**

If cosθ=(3/5) and 0<

θ=0.927295218

If cosθ=(3/5) and 0<

**θ<2pi**

determine the value of sin[determine the value of sin[

**θ+(pi/6)]**

Attempt:

Attempt:

**θ=cos^-1(3/5)**θ=0.927295218

**sin[**

How do i find the second value, all i can find is

**θ+(pi/6)]=0.992820323**

real answer = 0.992820323, -0.39282real answer = 0.992820323, -0.39282

How do i find the second value, all i can find is

**0.992820323 but not -0.39282**
