Latex has … NettetSo if you integrate over C and C is the circumference of the circle, then the limits of integration should be 2*pi*r, where r is the radius of the circle in meters. So in this case it is 1 meter to make it simple, so r =1 meter. And the force opposing the movement of the particle is in N, so you get 2 pi Nm. NettetAn online LaTeX editor that’s easy to use.

NettetAll right we're going from x equals negative six to x equals negative two, and the definite integral is going to be the area below our graph and above the x-axis. So it's going to be this area right over here. And how do we figure that out? Well this is a semicircle, and we know how to find the area of a circle if we know its radius. NettetYes. You‘ll likely see only one integral sign with the circle and a subscript letter that describes the surface or stuff like that. Depends on the author. Some also just don‘t do the circle. It‘s a matter of taste.
