Reminder: $(\text{sin }θ)^2$ is usually written as $\text{sin}^2 θ$. However, the first form must be used on your calculator. Also, $\text{sin }θ^2$ means to square $θ$ first and then take the sine. If $\text{sin }θ = 0.6$ and $\frac { \pi } { 2 }≤ θ ≤\pi$, find the following values or state “impossible without a calculator.”

1. $(\text{sin }θ)^2$

   Answer (a):

   This is $(0.6)(0.6)$: $0.36$

2. $\text{sin}^2 θ$

   Answer (b):

   This is the same as (a) above.

3. $\text{sin }θ^2$

   Answer (c):

   This is impossible because $θ$ is unknown.
