We'll have to find the lowest points of the "molar" plot, and we can do so by differentiation:
f ′ ( x ) = − cos ( x ) ∗ ( cos ( 1 / sin x ) ) / ( sin x ) 2 = 0
There are many values that give f'(x) = 0, but the 2 corresponding coordinates to the figure are (0.2138, -1) and (2.9278, -1).
If we set a new function g(x) = \sin(\csc(x))+1, the "molar" will rise above the x-axis, and we can simply calculate the area by using definite integral from 0.2138 to 2.9278:
So the area is roughly 4.74.
