Answer:

Step-by-step explanation:
Recall the negative angle identity for the sine function:
Then, we can find the value of
:

Now recall the definition of the tangent function:

Therefore, now that we know the value of
, we can solve in this equation for 

Answer:x=-1
Step-by-step explanation:
Given that f(x)=2sin(x+π), the standard form of sine function is y=A=sin(Bx+C), with:
A=amplitude
2π/B=period
C/B=phase-shift
A=2=amplitude
B=1
period=2π/B=2π/1=2π
C=2π/1=2π
