Homework Statement
im not sure the elegant way to put it, i need to integrate this somehow (ie, throw over the dt and integrate each side) but that squared is really tripping me up. is there a trick i should be using?
-g(cos(x))=r(dx/dt)^2
Homework Equations
The Attempt at a Solution
my attempt was initially to integrate 1/(cos(x))^(1/2), that is not pretty
i heard classmates talking about multiplying though by (dx/dt), not sure if that applies
any help appreciated, thanks!
