So this first wants you to find where sin is √3/2 when θ is between π and 3π/2. θ would therefore be located at 2π/3.
Now plug in the value of θ for cosine:
cos (2π/3) = -1/2
And tangent:
tan (2π/3) = -√3/3
Answer:
phase shift and period change

The formula for t would be x/7.
In order to find this, we simply follow the order of operations to solve for t.
7t = x ----> Divide both sides by 7
t = x/7
2(2/5+1/5)=2•3/5=6/5=1 1/5
Answer is C
