Homework Statement



[tex]\frac{dz}{d\theta}[/tex] = [tex]\int\sqrt{a^{2} + z'^{2}}[/tex]

I think I would have to make a substitution but I'm not sure which one to make...
 
Welcome to PF!

Hi martinhiggs! Welcome to PF! :smile:

(have a theta: θ and a square-root: √ and an integral: ∫ :wink:)

I'm confused :redface: …

What is z' ? And what is the d(something) inside the ∫ ? :confused:
