As per above question their is basic form used:
sin(2x) - √3 sin(x)
2sin(x) cos(x) - √3 sin(x)
Sin(x) (2cos(x) - √3)
To find its root let's equate it to zero
Sin(x) (2cos(x) - √3) = 0
Either, Sin(x) = 0 or cos(x) = √3 / 2
CAlculate its root.
Now the graph is
For area integrate the curve from a to b with its values obtained respectively.
Also it is periodic function in x with period 2π
