Two trig identities are of interest here:
... sin(x)² + cos(x)² = 1
... csc(x) = 1/sin(x)
Using the first one, you can subtract cos(x)², the take the square root to find
... sin(x) = ±√(1 - cos(x)²)
Using that in the second one, you have
... csc(x) = ±1/√(1 - cos(x)²) . . . . . . . . . . . . . matches the 3rd choice
The New South movement was an effort by southern leaders to integrate the South more fully with the rest of the US and to do away with the old plantation-based economy. It largely failed to gain significant momentum in terms of race relations and economic development by WWI.
I'm sure its C
Hope I got it right!
I think it is b. Iroquois
