A semicircular loop of radius a carries positive charge Q....
that's why I'm confused... I don't think I explained it properly but... I know the vector adding is what I'm looking for.. I just don't know how to get there from the integral equation and... I saw the two differentials dE and dtheta in my integral, that's why I'm confused because I understand...- robren

A semicircular loop of radius a carries positive charge Q....
Homework Statement A semicircular loop of radius a carries positive charge Q distributed uniformly... Find the electric field at the loop's center (point P in the figure). Hint: Divide the loop into charge elements dq as shown in the figure, and write dq in terms of the angle dθ, then...- robren

Solve Chain Rule Equation: y=(tan^-1(6x))^2
Homework Statement y = (tan^-1(6x))^2 Homework Equations Chain Rule, power rule? The Attempt at a Solution Okay, so I did power rule to bring it to 2(tan^-1(6x)) Then, I know to use the chain rule... I get 2(tan^-1(6x)*(1/1+x^2)... I know u = 6x so I play 6 into x^2 and I get 6x^2... I see...- robren
