We will see that the solution in the given interval is: x = 0.349 radians.
<h3>How to solve equations with the variable in the argument of a cosine?</h3>
We want to solve:
cos(3*x) = 1/2
Here we must use the inverse cosine function, Acos(x). Remember that:
cos(Acos(x)) = Acos(cos(x)) = x.
If we apply that in both sides, we get:
Acos( cos(3x) ) = Acos(1/2)
3*x = Acos(1/2)
x = Acos(1/2)/3 = 0.349
So x is equal to 0.349 radians, which belongs to the given interval.

Ok so since each pie requires 3 cups of sugar, you would just multiply the x value by 3. For example for one pie three cups of sugar are needed, for two pies six cups of sugar are needed, for three pies nine cups of sugar are needed etc. Hopefully this helps!
