Question #175a1

Answer 1

I don't know what "the dandy" refers to. I'll use the sum and difference formulas.

Explanation:

`sin(A+-B) = sinAcosB+-cosAsinB`

So,

`sin(x+pi/3)+sin(x-pi/3) = 2sinxcos(pi/3) = sqrt3 sinx`

To solve the equation, we want

`sqrt3sinx = sqrt3/2`, so `sinx = 1/2` and `x = pi/6` or `(5pi)/6`
