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

How do i Simplify 252 ÷ 3-3(4)(1)?

Answer:

Step-by-step explanation:

Enter the expression into your calculator.

If you're doing this by hand, follow the Order of Operations. The expression is the difference of a quotient and a product. The quotient is on the left, so it is figured first.

252÷3 = 84

The product is figured next.

3(4)(1) = 12(1) = 12

Then the difference is figured:

84 -12 = 72

The simplified result is 72.
