The function 𝑓 is given by 𝑓𝑥=sin2𝑥−sin𝑥.
A) Rewrite 𝑓 using the "sine double angle formula" we learned before break.
B) Starting from the rewritten version of this function, solve 𝑓𝑥=0 over the interval 0,2𝜋.
C) Solve 𝑓𝑥=0 over the interval −𝜋,𝜋 
D) Find all input values in the domain of 𝑓 for which 𝑓𝑥=0.
