In a textbook I'm reading, a step in an example problem was skipped during integration, and I'm just not quite seeing how to get from "point A to B" in this.
(1) d(R)/(2*cos(x)) = (R*d(x))/(sin(x))
(2) d(R)/R = 2*d(sin(x))/(sin(x))
*Integrate* (here is where I get lost -- what is happening here?)
(3) R = (sin(x))^2
(1) d(R)/(2*cos(x)) = (R*d(x))/(sin(x))
(2) d(R)/R = 2*d(sin(x))/(sin(x))
*Integrate* (here is where I get lost -- what is happening here?)
(3) R = (sin(x))^2
