# sec x physics problem watch

1. http://i-want-to-study-engineering.o...eird_resistor/
why is r=0.001secx?
2. You're told it's the shape of the sec curve so it's equation is going to be for some constant c. When x=0 the radius is 0.001, and since sec0 =1, it follows that c must be 0.001, and so r= 0.001secx

why is the radius= csecx?

why is the radius= csecx?
The radius at any given point is the height of the curve, since it's rotated about the x-axis.
